# How do you use an exponent to represent a number such as 16?

An exponent is defined as the number of times a given number is multiplied by itself. For example, 5^{3} means 5 is multiplied by itself 3 times.

## Answer: We can express 16 in exponential form as 2^{4} or 4^{2}.

Let us proceed step by step

**Explanation:**

The first step to write any number in exponential form is to do the prime factorization of the given number.

Here 16 can be prime factorized as 2 × 2 × 2 × 2

As we can see that 2 is multiplied 4 times so by using exponent we can write 16 as 2^{4}.

Where 2 is the base of the exponent and 4 is the power of the exponent.

We can also write 16 as 4 × 4 = 4^{2}
