Solution steps

9. 1^{9} \cdot 7. 1^{- 2}

Apply exponent rule:

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

= 9. 1^{9} \cdot \frac{1}{7. 1 ^{2}}

Multiply fractions:

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

= \frac{1 \cdot 9. 1 ^{9}}{7. 1 ^{2}}

Multiply:

1 \cdot 9. 1^{9} = 9. 1^{9}

= \frac{9. 1 ^{9}}{7. 1 ^{2}}

9. 1^{9} = 427929800.12978 \dots

= \frac{427929800.12978 \dots}{7. 1 ^{2}}

7. 1^{2} = 50.41
