simplify 4^{-2}*7^{-2}

Solution

simplify

4^{- 2} \cdot 7^{- 2}

Solution

\frac{1}{784}

+1

Decimal Notation

0.00127 \dots

Solution steps

4^{- 2} \cdot 7^{- 2}

4^{- 2} = \frac{1}{16}

= \frac{1}{16} \cdot 7^{- 2}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

7^{- 2} = \frac{1}{7 ^{2}}

= \frac{1}{16} \cdot \frac{1}{7 ^{2}}

7^{2} = 49

= \frac{1}{16} \cdot \frac{1}{49}

\frac{1}{16} \cdot \frac{1}{49} = \frac{1}{784}

= \frac{1}{784}
