Question 953728: Problems I am stuck on
a. Simpilfy +%283z%5E5%29%5E+%28++-++2_z%5E10%29++
b. Simplify the expression. Assume x denotes any real number
+root%286%2Cx%5E6%29+
My program states "x" is not the answer. I think it has something to do with assuming x denotes any real number so that might change it.
c. Simplify +root%283%2Csqrt%28729x%5E6%29%29+
Please explain
Thank you

You can put this solution on YOUR website!
(b), even value for root and exponent; looking for PLUS or MINUS x.

(c), can be a little easier looking as only EXPONENTS:

%28%28729%2Ax%5E6%29%5E%281%2F2%29%29%5E%281%2F3%29, which might not display well when rendered on the site. Know the Rules for Exponents.

%28729%5E%281%2F2%29%2Ax%5E%286%2A%281%2F2%29%29%29%5E%281%2F3%29

%2827%2Ax%5E3%29%5E%281%2F3%29

27%5E%281%2F3%29%2Ax%5E%283%2A%281%2F3%29%29
