simplify 9.4*2^{-2}

Solution

simplify

9.4 \cdot 2^{- 2}

\frac{47}{20}

Decimal Notation

2.35

Solution steps

9.4 \cdot 2^{- 2}

Apply exponent rule:

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

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

= 9.4 \cdot \frac{1}{2 ^{2}}

2^{2} = 4

= 9.4 \cdot \frac{1}{4}

9.4 = \frac{47}{5}

= \frac{47}{5} \cdot \frac{1}{4}

\frac{47}{5} \cdot \frac{1}{4} = \frac{47}{20}

= \frac{47}{20}
