Prove that if a & bare natural numbers such that GCF (a, b) = d & LCM (a,b) = m,then ab = dm.
Assistant: Let's address each of your questions step by step.

1. *Convert the decimal 0.314 to fraction form:*
   - To convert the decimal 0.314 to a fraction, we can express it as:
     \[
     0.314 = \frac{314}{1000}
     \]
   - Next, we simplify the fraction:
     \[
     \frac{314}{1000} = \frac{157}{500}
     \]
   - Thus, \(0.314\) as a fraction is \(\frac{157}{500}\).

2. *Convert the non-terminating periodic decimal 12.036 to fraction form:*
   - Let \(x = 12.036363...\)
   - To eliminate the repeating part, we multiply by 1000 (to shift three decimal places):
     \[
     1000x = 12036.363636...
     \]
   - Then, we multiply by 100 (to shift two decimal places):
     \[
     100x = 1203.636363...
     \]
   - Now, we subtract the second equation from the first:
     \[
     1000x - 100x = 12036.363636... - 1203.636363...
     \]
     \[
     900x = 10833
     \]
     \[
     x = \frac{10833}{900} = \frac{1209}{100}
     \]
   - So, the fraction form of \(12.036\) is \(\frac{1209}{100}\).

3. *Prove by mathematical induction that for all \(n \in \mathbb{N}\), \(1^3 + 2^3 + 3^3 + ... + n^3 = \left( \frac{n(n+1)}{2} \right)^2\):*
   - *Base case (n=1):*
     \[
     1^3 = 1 = \left( \frac{1(1+1)}{2} \right)^2 = 1
     \]
   - *Inductive step:*
   Assume true for \(n=k\):
   \[
   1^3 + 2^3 + ... + k^3 = \left( \frac{k(k+1)}{2} \right)^2
   \]
   Now for \(n=k+1\):
   \[
   1^3 + 2^3 + ... + k^3 + (k+1)^3 = \left( \frac{k(k+1)}{2} \right)^2 + (k+1)^3
   \]
   Let's simplify this:
   \[
   = \left( \frac{k(k+1)}{2} \right)^2 + (k+1)^3 = (k+1)^2 \left( \left( \frac{k}{2} \right)^2 + (k+1) \right)
   \]
   Simplifying leads to:
   \[
   = (k+1)^2 \cdot \frac{(k^2 + 4k + 4)}{4} = \left( \frac{(k+1)(k+2)}{2} \right)^2
   \]
   This completes the proof.

4. *Find an odd natural number \(x\) such that LCM(x, 40) = 1400:*
   - The prime factorizations:
     \[
     40 = 2^3 \cdot 5^1
     \]
     \[
     1400 = 2^2 \cdot 5^2 \cdot 7^1
     \]
   - For the LCM to equal 1400, \(x\) must provide the necessary primes:
     - Since \(x\) is odd, it cannot provide any \(2\)s.
     - To satisfy LCM, \(x\) must have at least \(5^2\) and \(7^1\):
     - Thus:
     \[
     x = 5^2 \cdot 7^1 = 25 \cdot 7 = 175
     \]

5. *The GCF of two numbers is 3 and their LCM is 180. If one of the numbers is 45, find the second number:*
   - Using the relationship \( \text{GCF}(a, b) \times \text{LCM}(a, b) = a \times b \):
   - Let \(b\) be the unknown number:
   \[
   3 \times 180 = 45 \times b \implies 540 = 45b \implies b = \frac{540}{45} = 12
   \]

6. *Prove that if \(a\) and \(b\) are natural numbers such that GCF(a, b) = d and LCM(a, b) = m, then \(ab = dm\):*
   - From the definitions, we have:
   \[
   a = dx \quad \text{and} \quad b = dy \quad \text{where GCD}(x, y) = 1
   \]
   - Then,
   \[
   ab = (dx)(dy) = d^2xy
   \]
   - For LCM:
   \[
   \text{LCM}(a, b) = \frac{ab}{\text{GCF}(a, b)} = \frac{d^2xy}{d} = dxy
   \]
   - Therefore:
   \[
   m = dxy \implies ab = dm
   \]

User: Please sent the answer by shorter method
Assistant: Sure! Here are the answers presented in a more concise manner:

1. *0.314 as a fraction:*  
   \(0.314 = \frac{157}{500}\)

2. *12.036 as a fraction:*  
   \(12.036 = \frac{1209}{100}\)

3. *Inductive proof for \(1^3 + 2^3 + ... + n^3 = \left( \frac{n(n+1)}{2} \right)^2\):*  
   _Base case:_ \(n=1\) holds.  
   _Inductive step:_ Assume true for \(k\); prove for \(k+1\). 

4. *Odd \(x\) such that LCM(x, 40) = 1400:*  
   \(x = 175\)

5. *Second number when GCF is 3, LCM is 180, and one number is 45:*  
   Second number = \(12\)

6. *Proof for \(ab = dm\) if GCF(a, b) = d and LCM(a, b) = m:*  
   From definitions, \(ab = d^2xy\) and \(m = dxy\) imply \(ab = dm\).

Assistant: Let’s streamline the responses for each question:

11. _If \(\sin 8\) and \(\tan\), where \(\min = 0\), then \(\cos\) is equivalent to:_  
   *Not enough context provided. Please clarify!*

12. _Solve \(3x + 7 - 2(5x - 4) = 15\):_  
   \[
   3x + 7 - 10x + 8 = 15 \implies -7x + 15 = 15 \implies x = 0  
   \]  
   *Solution set: \((0)\)*

13. _Let \(f(x) = ...\). The inverse function of \(f\) is:_  
   *Not enough context provided for \(f(x)\). Please clarify!*

14. _Let \(f(x) = 2x^2 - ax^2 + 3x - b\). If -7 is the remainder when f(x) is divided by \(x + 1\) and \(f(2) = 1\):_  
   - For \(f(-1) = -7\) (Remainder):  
     \[
     f(-1) = 2(-1)^2 - a(-1)^2 + 3(-1) - b = -7 \implies 2 - a - 3 - b = -7 \implies -a - b = -6  
     \]
   - For \(f(2) = 1\):  
     \[
     f(2) = 2(2)^2 - a(2)^2 + 3(2) - b = 1 \implies 8 - 4a + 6 - b = 1 \implies -4a - b = -13  
     \]

   Solving these gives \(a = 7\) and \(b = -5\).  
   *Answer: (A) 7, -5*

15. _Vertical and horizontal asymptotes for \(f(x) = 25\):_  
   - This is a constant function, thus:  
   *Vertical: none; Horizontal: y = 25.*  
   *No option matches perfectly—please clarify!*

16. _If \(x + 2\) is a factor of \(ax - 2x + 43 - 8x - 8\):_  
   First simplify:
   \[
   f(x) = ax - 10x + 35 \implies (a - 10)(-2) + 35 = 0  
   \]  
   Thus \(a = 4\).  
   *Answer: (A) 4*

17. _The solution set of \(x + 5\):_  
   \[
   x + 5 = 0 \implies x = -5  
   \]  
   *Solution set: \((-5)\)*
