Z^5/8
You can tell this because exponents get added together when multiplying and the fact that the fraction goes down by a multiple of 1/8.
Your answer is y ≥ −10 + 5x/2
8 as that means what two of the same number makes up , in this case 64. 8x8=64
I dont think the answer is 129 unless you typed the problem in wrong. Order of operations say to do everything inside the perenthesis first so you would do the 3*2 which is 6 then divide the 12 by 6 and you get 2. so your new equation is 8^2+9(2)-7. Next distribute the 9 to the 2 that is inside the perenthesis. Square root the 8 also. Now it is 49+18-7. The answer would be 60 ...?
(x^3 - y^3)(x^3 + y^3)
You can get this by factoring based on the a^2 - b^2 model
