The remainder of $3^{20}$ divided by 5 is __________.

Okay, let's see. I need to find the remainder when 3^20 is divided by 5. Hmm, modular arithmetic, right? So 3^20 mod 5. I remember that there's something called Fermat's little theorem, but maybe I can do it with patterns of remainders. First, let's list
3^n mod 5 for small n to see if there's a cycle. 3^1 = 3, so 3 mod 5 is 3. 3^2 = 9, 9 mod 5 is 4. 3^3 = 27, 27 mod 5 is 2 (since 5*5=25, 27-25=2). 3^4 = 81, 81 mod 5 is 1 (because 5*16=80, 81-80=1). Oh, so the cycle length here is 4. Because 3^4 mod 5 is 1, so the powers of 3 modulo 5 repeat every 4. So 3^4 ≡ 1 m...

A + (y²)/B = 1 to be a hyperbola with foci on the y-axis, we need A to be negative and B to be positive. That way, the equation can be rewritten as (y²)/B - (x²)/(-A) = 1, which is the standard form of a hyperbola opening up and down. Let's write down the denominators here.

Given sets $A = \{x\,|\,x < -1 \text{ or } 2 \leq x < 3\}$ and $B = \{x\,|\,-2 \leq x < 4\}$, find the union $A \cup B$.
\\{x | x < 4\\}
Okay, let's try to solve this problem. So, we have two sets A and B, and we need to find their union. First, I need to remember what the union of two sets means. The union A ∪ B is all the elements that are in A, in B, or in both. So, I should probably write out what each set looks like on a number line and then see wh...
2 is in A? Wait, no. Let's be precise. Let's list the intervals: A: (-∞, -1) ∪ [2, 3) B: [-2, 4) So the union would be the combination of these. Let's see. The B set starts at -2, so the leftmost part of the union should be -2, since B goes down to -2. Then A has up to -1, so from -2 to -1 is covered by B (since B ...

2 ≤ x < 3 is part of A, and x < -1 is part of A. B is from -2 to 4, so B includes from -2 to 3 (since A's second interval is 2 to 3) and then 3 to 4.

2's interval is part of A. Wait, no: A is two separate intervals. So A is (-∞, -1) ∪ [2, 3). B is [-2, 4). So when we take the union, we need to see how these intervals connect.

x in [-2, -1) are in A? Wait, no. Wait, A is x < -1, so that's all numbers less than -1, which includes [-2, -1). Because -2 is less than -1, so [-2, -1) is part of A.

1, I can solve for one variable in terms of the other. Let's solve for y. So, y/4 = 1 - x/3, which means y = 4(1 - x/3) = 4 - (4x)/3. Since x and y are positive, x has to be between 0 and 3, right? Because if x is 3, then y would be 0, and if x is 0, y is 4. So x ∈ (0, 3), y ∈ (0, 4). Now, we need to maximize xy. So s...

Okay, let's see. I need to find the greatest common divisor (GCD) of 459 and 357 using the method of successive subtraction. Hmm, I remember that the method of successive subtraction involves subtracting the smaller number from the larger one repeatedly until both numbers become equal. That common value is the GCD. Let...
subtraction: 459 - 357. Let's calculate that. 459 minus 300 is 159, then minus 57 more is 102. So 459 - 357 = 102. Now the two numbers are 357 and 102. Next, I need to subtract the smaller number (102) from the larger one (357). Let's do that: 357 - 102. 357 minus 100 is 257, minus 2 more is 255. So 357 - 102 = 255. ...

Let's calculate that. 357 divided by 102 is 3 times (since 102*3=306), so 357 - 306 = 51. Now we have 102 and 51. Now, 102 is larg...
