if p and q are prime numbers , how many divisors does the product p ^ 2 * q ^ 5 have ?
"when a number n = a ^ x * b ^ y , where a and b are prime numbers , and x , y are positive integers , the number of divisors of n = ( x + 1 ) ( y + 1 ) therefore , the answer is e . 3 * 6 = 18"
multiply(add(2, const_1), add(5, const_1))
