Solution

4.91769 \dots

Solution steps

7.2 (1.1)^{- 4}

Apply exponent rule:

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

= 7.2 \cdot \frac{1}{1. 1 ^{4}}

Multiply fractions:

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

= \frac{1 \cdot 7.2}{1. 1 ^{4}}

Multiply the numbers:

1 \cdot 7.2 = 7.2

= \frac{7.2}{1. 1 ^{4}}

1. 1^{4} = 1.4641

Divide the numbers:

\frac{7.2}{1.4641} = 4.91769 \dots

= 4.91769 \dots
