0.79683 \dots

Solution steps

5 (1.3)^{- 7}

Apply exponent rule:

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

= 5 \cdot \frac{1}{1. 3 ^{7}}

Multiply fractions:

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

= \frac{1 \cdot 5}{1. 3 ^{7}}

Multiply the numbers:

1 \cdot 5 = 5

= \frac{5}{1. 3 ^{7}}

1. 3^{7} = 6.2748517

= \frac{5}{6.2748517}

Divide the numbers:

\frac{5}{6.2748517} = 0.79683 \dots
