simplify 1.4*0.75^{-2}

Solution

simplify

1.4 \cdot 0.7 5^{- 2}

Solution

2.48888 \dots

Solution steps

1.4 \cdot 0.7 5^{- 2}

Apply exponent rule:

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

= 1.4 \cdot \frac{1}{0.7 5 ^{2}}

Multiply fractions:

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

= \frac{1 \cdot 1.4}{0.7 5 ^{2}}

Multiply the numbers:

1 \cdot 1.4 = 1.4

= \frac{1.4}{0.7 5 ^{2}}

0.7 5^{2} = 0.5625

= \frac{1.4}{0.5625}

Divide the numbers:

\frac{1.4}{0.5625} = 2.48888 \dots

= 2.48888 \dots
