Answer
$3^{5}\times 14^{2}$.
Work Step by Step
When we write a number using exponents, we write the number and then put the exponent above it; this exponent tells us how many times to multiply that number by itself. Here, we see that 14 is multiplied by itself 2 times, and 3 is multiplied by itself 5 times, so we know that the answer should be: $3^{5}\times 14^{2}$.
