Question

I'm having an issue solving my question. Can someone help?
[15-20/2(2)]^-3

Answer 1

\[\left[ 15-20\div2(2) \right]^{-3}\]

Answer 2

I ended up getting 1/125 as my final answer. I'm not entirely sure if that is correct. I'm getting frusterated.

Answer 3

it is hard to read, but i don't think that is right

Answer 4

\(2\times 2=4, 20\div 4=5, 15-5=10, 10^{-3}=0.001\)

Answer 5

But remember order of operations. 20/4 should come first and then 2x2. Then 1515-20

Answer 6

i got -1/75
