Question

(3x³y⁵)^{2   (}x²y³)^-2

 

perform the indicated operation and simplify as needed. HELP!

Answer 1

exponentiation of the terms enclosed in parentheses first

 

(9x⁶y¹⁰)  (x^-4y^-6)       technically, parentheses are no longer needed, but they show where the new terms came from 

 

= 9x^6-4y^10-6

 

= 9x²y⁴
