Simplify:
4^(-1/2)
4-1/2 = 1/41/2 = 1/2. check my work.
On exponents, negative means reciprocal.
4(-1/2) means the same as
1/4(1/2) which is the same as
1/squareroot(4)
so the answer is 1^4
no, of course not. The square root of 4 is 2 isn't it?
so 1/squareroot(4) = 1/2.
oh lol thanks can you help me with proofs?
