Powers of Products and Quotients

Learn how to take a product or a quotient to power by using powers of products and quotients rules.

Step by step guide to solve powers of products and quotients

  • For any nonzero numbers \(a\) and \(b\) and any integer \(x\),
    \(\color{blue}{(ab)^x=a^x×b^x}\).

Example 1:

Simplify. \((6x^2 y^4)^2=\)

Solution:

Use Exponent’s rules: \(\color{blue}{(ab)^x=a^x×b^x}\)
\((6x^2y^4)^2=(6)^2(x^2)^2(y^4)^2=36x^{2×2}y^{4×2}=36x^4y^8\)

Example 2:

Simplify. \((\frac{5x}{2x^2})^2=\)

Solution:

First cancel the common factor: \(x→ (\frac{5x}{2x^2} )^2=(\frac{5}{2x})^2 \)
Use Exponent’s rules: \(\color{blue}{(\frac{a}{b})^c=\frac{a^c}{b^c}}\)
Then: \((\frac{5}{2x})^2=\frac{5^2}{(2x)^2} =\frac{25}{4x^2}\)

Example 3:

Simplify. \((3x^5 y^4)^2=\)

Solution:

Use Exponent’s rules: \(\color{ blue }{(x^a)^b=x^{a×b}}\)
\((3x^5 y^4)^2=(3)^2 (x^5)^2 (y^4)^2=9x^{5×2} y^{4×2}=9x^{10} y^8 \)

Example 4:

Simplify. \((\frac{2x}{3x^2} )^2=\)

Solution:

First cancel the common factor: \(x→ (\frac{2x}{3x^2} )^2=(\frac{2}{3x})^2 \)
Use Exponent’s rules: \(\color{blue}{(\frac{a}{b})^c=\frac{a^c}{b^c}}\)
Then: \((\frac{2}{3x})^2=\frac{2^2}{(3x)^2 }=\frac{4}{9x^2 }\)
