Question

Evaluate 12x^2 y^-1 for x = 3 and y = 4


-27
27
324

Answer 1

Your answer will be 27

Okay, then if x=3 and y=4, then the new expression is (12x9)(0.25). If you solve that you'll get 27, since 12x9=108 and 1/4 of 108=27

Answer 2

`12x^2 y^(-1)`

Plug given values of x = 3 and y = 4

`=12(3)^2 (4)^(-1)`

`=12(9) *(1)/(4)`

`=(108)/(4)`

`=27`

Hence final answer is 27.
