Does anyone know the the answer to the second algebra question? Will give brainiest

astraxan [27]

Answer:

$\sqrt[3]{x^{10} }[\tex]Step-by-step explanation:Exponential Rules:[tex]x^{a} + x^{b} = x^{a + b}$

$\sqrt[b]{x^{a} } =x^{\frac{a}{b} } Original Equation:[tex]\sqrt[3]{x^{10} } = x^{\frac{10}{3} } Answer:[tex]\sqrt[3]{x^{10} }[\tex]Convert the cubed root to a power. Cubed root = [tex]\frac{1}{3}$

$x^{3} x^{\frac{1}{3} }$

Convert them, so they have a common denominator - $\frac{1}{3}$

$\frac{3}{1} * \frac{1}{3}= \frac{9}{3}$

$\frac{9}{3} + \frac{1}{3} = \frac{10}{3}$

[tex]\sqrt[3]{x^{10} }[\tex] = [tex]x^{\frac{10}{3} } [\tex]

How to simplify this so it equal to c

alukav5142 [94]

Combine terms using exponent rules:
$a^m *a^n = a^{m+n} \\ \\ \frac{a^m}{a^n} = a^{m-n}$

First rewrite everything so that you have 2^m terms and x^m terms

$\frac{2^4 x^4 x^{3/2}}{2^{5/2} x^{5/2}} \\ \\ = 2^{4 - (5/2)} * x^{4 + (3/2)-(5/2)} \\ \\ =2^{(3/2)} x^{(6/2)} \\ \\ = 2 \sqrt{2} x^3$
