Week 9 Rational Exponents & Radicals

Copy down and show work for each question on a piece of scratch paper. Please be organized! Use pg. 65 and 66 for help. If you do not have these pages, grab a copy from the front table and check out the answer keys posted to Google Classroom. You will be graded on your scratch paper, not your Quizizz score.

Fully Simplify:

TIP: Step 1 = Negative exponent needs to move to the denominator! The 18 will stay as the numerator.

• -54

• 6
