Simplify, Write your answer in exponential notation.<br> a.) 2³ x 2-5<br> b.) (602)3
mariarad [96]

The simplified expressions are 2^-2 and 60^6

<h3>How to simplify the expressions?</h3>

<u>Expression (a)</u>

We have:

2^3 * 2^-5

Apply the product law of indices

2^3 * 2^-5 = 2^(3 - 5)

Evaluate the difference

2^3 * 2^-5 = 2^-2

<u>Expression (b)</u>

We have:

(60^2)^3

Apply the power law of indices

(60^2)^3 = 60^(2 * 3)

Evaluate the product

(60^2)^3 = 60^6

Hence, the simplified expressions are 2^-2 and 60^6
