Question 8052
{{{sqrt(9a^2b^6)}}}


{{{sqrt(9)sqrt(a^2)sqrt(b^6)}}}
+{{{3(a^2)^(1/2)(b^6)^(1/2)}}} or -{{{3(a^2)^(1/2)(b^6)^(1/2)}}}

writing it this way shows you what to do..the powers multiply together, to give:
+{{{3(a^1)(b^3)}}} or -{{{3(a^1)(b^3)}}}


so, final answer is:
+{{{3a(b^3)}}} or -{{{3a(b^3)}}}
