+409 Solve the following equations for x:
a) √2x = -7
Combine radicals, if possible. Simplify your answer as much as possible.
^3√2x + 9^3√2x - 2^3√2x =
Simplify the following expression as much as possible. Assume that all variables are positive.
^3√8x^16y^4 / ^3√125x^4y =
+137 I think \(^3√2x + 9^3√2x - 2^3√2x\) = \(\left(-1\right)^{\frac{1}{3}}*7^{\frac{1}{3}}+40824\)
