\frac{a^{12}b^{8}}{a^{2}b^{4}}



remember
(ab)/(cd)=a/c times b/d

also \frac{x^{m}}{x^{n}}= x^{m-n}

split it up with like terms

\frac{a^{12}}{a^{2}} times \frac{b^{8}}{b^{4}}

do subtraction
for a's
12-2=10

b's
8-4=4

answe is a^{10}b^{4}

first one

What is the simplest form of the product cube root4x^2*cube root8x^7
Illusion [34]

Answer:

f(x) =  2^{\frac{5}{3} }x^{3} is the simplest expression

Step-by-step explanation:

We are given an expression and we are supposed to find the simplest form of the given expression.

The given expression is

f(x) = \sqrt[3]{4x^{2} } \times \sqrt[3]{8x^{7} }

Since the cube root is common we can multiply the quotient inside the radical sign.

f(x) = \sqrt[3]{32x^{(2+7)} }

     = \sqrt[3]{32x^{9} }

     = 2^{\frac{5}{3} }\times x^{\frac{9}{3} }

     = 2^{\frac{5}{3} }x^{3}

f(x) =  2^{\frac{5}{3} }x^{3} is the simplest expression
