Are the last 2's exponents? That would mean you want to know

[8(x^3y^4)^2]^-2

The +2 and -2 operations on (x^3y^4) would leave it unchanged, and leave you with

(1/64)(x^3y^4)

The 2's are not exponents

Apologies to you and James B, I'm home from work now and just looked at the problem and the 2's are exponents.

The problem to solve is:

(8(x^3y^4)2)-2

Multiply 8 and

8*(x^3*y^4)2 evaluates to 64

Abort (8*(x^3*y^4)2)-2 evaluates to 64-64

The final answer is 64-64

If the 2's are exponents, I stand by my original answer.
