For #1 you need to take the square root of 9/121, then once you have that you cube it : )
square root 9/121 = 3/11
then (3/11)(3/11)(3/11) as that is what the power of three (or cubing it means), it means do it out three times : )
Now what do you get??
1. simplify
(9/121) ^ 3/2
i got 13.5/181.5 but it is wrong
2.
16 ^1/4 - 49 ^1/2
I got -3, but it is wrong
thank you!
