simplify 0.4a^0*0.7^{-4}

Solution

simplify

0.4 a^{0} \cdot 0. 7^{- 4}

Solution

1.66597 \dots

Solution steps

0.4 a^{0} \cdot 0. 7^{- 4}

Apply exponent rule:

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

= 0.4 \cdot \frac{1}{0. 7 ^{4}} a^{0}

Apply rule

a^{0} = 1, a \neq = 0

a^{0} = 1

= 1 \cdot 0.4 \cdot \frac{1}{0. 7 ^{4}}

Multiply the numbers:

0.4 \cdot 1 = 0.4

= 0.4 \cdot \frac{1}{0. 7 ^{4}}

Multiply fractions:

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

= \frac{1 \cdot 0.4}{0. 7 ^{4}}

Refine

= \frac{0.4}{0.2401}

Divide the numbers:

\frac{0.4}{0.2401} = 1.66597 \dots

= 1.66597 \dots
