Solution

simplify

4 (1.2)^{- 5}

Solution

1.60751 \dots

Solution steps

4 (1.2)^{- 5}

Apply exponent rule:

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

= 4 \cdot \frac{1}{1. 2 ^{5}}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 4}{1. 2 ^{5}}

Multiply the numbers:

1 \cdot 4 = 4

= \frac{4}{1. 2 ^{5}}

1. 2^{5} = 2.48832

= \frac{4}{2.48832}

Divide the numbers:

\frac{4}{2.48832} = 1.60751 \dots

= 1.60751 \dots
