Question

Evaluate (1/4)^—2-(5^0x 2)x1^-1

Answer 1

This expression is awkward.  Your (1/4)^--2 should be written (1/4)^(-2).
Also, your x 2 should be written x^2 (the square of x).

But maybe that's not what you meant!

Your apparent use of "x" to indicate "multiply" makes things harder and more confusing.  Please use " * " ONLY to denote multiplication.  

Let's try again.  Here's what I think I see:

(1/4)^(-2)    -    1*2*1^(-1)                  and here is the evaluation:

16               -      2              =    32

Practice typing in expressions like these and then try to get some critique from your teacher regarding where you are correct and where you are not.
