simplify 4(2.4+5)*10^{-2}

Solution

simplify

4 (2.4 + 5) \cdot 1 0^{- 2}

Solution

0.296

Solution steps

4 (2.4 + 5) \cdot 1 0^{- 2}

Add the numbers:

2.4 + 5 = 7.4

= 4 \cdot 7.4 \cdot 1 0^{- 2}

Apply exponent rule:

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

1 0^{- 2} = \frac{1}{1 0 ^{2}}

= 4 \cdot 7.4 \cdot \frac{1}{1 0 ^{2}}

1 0^{2} = 100

= 4 \cdot 7.4 \cdot \frac{1}{100}

Multiply the numbers:

4 \cdot 7.4 = 29.6

= 29.6 \cdot \frac{1}{100}

= \frac{1}{100} \cdot 29.6

\frac{1}{100} \cdot 29.6 = \frac{29.6}{100}

= \frac{29.6}{100}

Divide the numbers:

\frac{29.6}{100} = 0.296

= 0.296
