simplify 2(4)^{-2}

Solution

simplify

2 (4)^{- 2}

\frac{1}{8}

Decimal Notation

0.125

Solution steps

2 \cdot 4^{- 2}

Apply exponent rule:

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

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

= 2 \cdot \frac{1}{4 ^{2}}

4^{2} = 16

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

2 \cdot \frac{1}{16} = \frac{1}{8}

= \frac{1}{8}

(\frac{8}{3})^{- 2}

\frac{\frac{1}{r} + \frac{1}{s}}{\frac{1}{r ^{2}} - \frac{1}{s ^{2}}}

4 = - \frac{5}{4} (- 6) + b

(2 i)^{5} \cdot (i 6)^{2}

410 \cdot 36
