**Ashley**, Saturday, September 8, 2012 at 2:49pm(-5)^4 should be (-5)*(-5)*(-5)*(-5)

for -(10)^2 was the negitive attached to the ten if so its (-10)*(-10) if not then its (10)*(10)*(-1)

= -(10)*(10)

the rest are correct , you already corrected (-5)^4

**marko**, Saturday, September 8, 2012 at 2:59pmwait for : -(10)^2

the negative sign is outside to left of parenthesis

so is it:

(10)*(10)*(-1)

is that right?

It does not matter whether the -1 is in front or behind

-(10)(10) = -1(10)(10) = (10)(10)(-1)
