what is x^z?

anonymous · Answer

it was in the problem

anonymous · Answer

its a variable

anonymous · Answer

then this problem cannot be factored.

anonymous · Answer

the answer is x-1 but idk how that is

anonymous · Answer

if z =2, then the answer is x-1

anonymous · Answer

how did u get that?

anonymous · Answer

substitute z = 2 and solve. you will get x-1

anonymous · Answer

$$(x ^{3}+x) \div (x ^{2}+x) = x(x ^{2}+1) \div x(x+1) = (x ^{2}+1) \div (x+1)$$

anonymous · Answer

$$(x ^{2}-1) \div (x ^{2}+1) = (x-1)(x+1) \div (x ^{2}+1)$$

anonymous · Answer

multiply both, you cancel out x^2+1 and x+1, you are left with x-1

anonymous · Answer

k let me attach the file bc i think the 2 is a z

anonymous · Answer

ok

anonymous · Answer

you will get the answer x-1 only if z = 2
