How would you simplify
1) (5a^2b^3c^-1/2^-1abc^-1)^2
2) (2/3) (2/3)^-1 (2/3)^-2 (2/3)^5
3) (3xy/z)^3
multiply each of the powers by 2 and then simplify
this is (2/3) raised to the sum of all the powers (remember, if you don't see a power written, then the power is 1). then simplify if you can2) (2/3) (2/3)^-1 (2/3)^-2 (2/3)^5
again, multiply all the powers by 33) (3xy/z)^3
can you continue?
here we used the rules:
(this of course implies )
and
