You can put this solution on YOUR website! I need help sovling this problem. I need steps in words as well as the math. Please help I nee to know how to do this.
(81a^12 b^16)^-1/2
-------------------------
The exponent has two instructions:
#1: the negative means "invert"
#2: the 1/2 means "take the square root"
-----------------------------
You may do the instructions in any order and get the same answer:
--------------------------------------
So,
Take the square root and you get:
(9*a^6*b^8)^-1
---
Now,
Invert to get:
1/(9a^6 * b^8)
