Answer 3

\(\bf {\color{blue}{ a^n\cdot a^m\implies a^{n+m}}}\\ \quad \\ \quad \\
32\sqrt{x\cdot x^2\cdot x^5}\implies 32\sqrt{x^1\cdot x^2\cdot x^5}\implies 32\sqrt{x^{1+2+5}}\)

Answer 4

so... um x^8 is under the radicand bar, right?

Answer 5

recall the exponents rule, same base, different exponents, add the exponents, keep the base -> http://www.math-play.com/image-exponents-rules.jpg

yes, will be \(x^8\)

Answer 6

how do I do 32sqrt(x^8)?

Answer 7

then take out what you can from the radicand :)

Answer 8

\(\bf {\color{blue}{ a^n\cdot a^m\implies a^{n+m}}}\\ \quad \\ \quad \\
32\sqrt{x\cdot x^2\cdot x^5}\implies 32\sqrt{x^1\cdot x^2\cdot x^5}\implies 32\sqrt{x^{1+2+5}}\\ \quad \\
32\sqrt{x^8}\implies \large 32\sqrt[{\color{red}{ 2}}]{(x^4)^{\color{red}{ 2}}}\)

Answer 9

so... um 32x^4???
