on your calculator look for key labeled
yx or xy or sometimes ab
enter:
32
press that key
1.2
=
you should get 64
BUT, I think you are meant to do these without a calculator, since all three are set as simple cases.
32^1.2
= (2^5)1.2
= 2^6
= 64
(-216)^(-2/3)
= 1/( (-216)^(2/3) )
= 1/( -216^(1/3)^2 )
= 1/ (-6)^2
= 1/36
you try the last one
Simplify the following:
1) 32^1.2
2) (-216)^(-2/3)
3) -(-27)^(-4/3)
Note: 32^1.2 is 32 raised to the 1.2 power
