√36√-36-^3√64?

Question

√36

√-36

-^3√64

evaluate each separately…………

Answer 1

why cant you do your own homework??
everyones wrong so far....

√36 = 6 or -6
√-36 = 6i or -6i
and if you mean -3√64 then its -24 or 24

Aside to BalRog:
I majored in math at MIT and have never seen the cube root expressed as stated. Since the poser of the question probably used the character map, -³√64 could have been used. I thought it was a typo. If you're goint to use the caret ^ for exponentiation, write it as -64^(1/3)

Answer 2

√36 = 6 or -6
√(-36) = 6i or -6i
-^3√64 = -4 or (2 + i2√3) or (2 - i2√3)

ASIDE TO Scott:
You are wrong too, the last one is a cube root. Read as "the negative of the cube root of sixty-four."

ASIDE TO tarfu:
Your square root answers do not take into account negative square roots, and your cube root answer does not take into account complex cube roots.

ASIDE TO edward:
Your square root answers do not take into account negative square roots, and your cube root answer does not even take into account the minus sign at the front of the expression.

ANOTHER ASIDE TO scott:
I myself have an MSci in Math (and a double BSci in Math and Physics), but we clearly are not in Kansas (U) anymore. In Yahoo Answers I have seen "^n" as the common substitute for all types of superscript notation, including "M^T" for matrix transposition. I really didn't think this notation was such a great barrier, but it seems to have nailed a number of people, not just you.

Answer 3

√36=6

√-36=6i

-^3√64=-^24 or if it is a cube root then -^(64)^(1/3)=4

Answer 4

6
6i
-4

Answer 5
