Question

PLEASE HELP MEEEEE!!!! I WILL GIVE YOU BRAINLIST AND POINTS

Answer 1

When you multiply numbers with the same base and exponents, you just add the exponents together. In the case of the first question:

$11^{2}$ * $11^{7}$ = $11^{9}$

When dividing, subtract the exponents instead, and when there's an exponent outside the parentheses the way it is on the 3rd question, multiply them together.

Hope this helps! :)
