Answer:

explanation in the attachment

hope it helps you!!

Answer 2

Answer:

142

Prime factorization of 142 = 2 * 71

Exponential form of 142 =  $2^{1} * 71^{1}$

128

Prime factorization= 2 x 2 x 2 x 2 x 2 x 2 x 2

Exponential form = $2^{7}$

1000

Prime factorization =  2 x 2 x 2 x 5 x 5 x 5

Exponential form = $2^{3} * 5^{3}$

396

Prime factorization=2 x 2 x 2 x 7 x 7

Exponential form = $2^{3} * 7^{2}$

216

Prime factorization = 2 x 2 x 2 x 3 x 3 x 3

Exponential form = $2^{3} * 3^{3}$

Step-by-step explanation:

**Prime factorization :**

                                   A factor that is a prime number. In other words: any of the prime numbers that can be multiplied to give the original number. Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers). See: Prime Number. Prime Factorization.

**What is simplified exponential form? **

                 Simplifying Exponential Expressions. Recall that to simplify an expression means to rewrite it by combing terms or exponents; in other words, to write the expression more simply with fewer terms. The rules for exponents may be combined to simplify expressions.
