simplify (-12.1)(1-54.07)^{-2}

simplify

(- 12.1) (1 - 54.07)^{- 2}

- 0.00429 \dots

Solution steps

(- 12.1) (1 - 54.07)^{- 2}

Apply exponent rule:

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

= (- 12.1) \frac{1}{( 1 - 54.07 ) ^{2}}

Remove parentheses:

(- a) = - a

= - 12.1 \cdot \frac{1}{( 1 - 54.07 ) ^{2}}

\frac{1}{( 1 - 54.07 ) ^{2}} = \frac{1}{53.0 7 ^{2}}

= - 12.1 \cdot \frac{1}{53.0 7 ^{2}}

Multiply fractions:

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

= - \frac{1 \cdot 12.1}{53.0 7 ^{2}}

Multiply the numbers:

1 \cdot 12.1 = 12.1

= - \frac{12.1}{53.0 7 ^{2}}

53.0 7^{2} = 2816.4249

= - \frac{12.1}{2816.4249}

Divide the numbers:

\frac{12.1}{2816.4249} = 0.00429 \dots

= - 0.00429 \dots
