if both 2 ^ 2 and 3 ^ 4 are factors of the number a * 4 ^ 3 * 6 ^ 2 * 13 ^ 11 , then what is the smallest possible value of a ?
"the number a must include at least 3 ^ 2 = 9 the answer is b ."
add(add(add(add(add(multiply(multiply(2, 2), 2), multiply(multiply(2, 2), 2)), multiply(multiply(2, 2), 2)), 2), const_4), const_4)
