simplify (1.410^{-4})(2.810^{-2})

simplify

(1.4 \cdot 1 0^{- 4}) (2.8 \cdot 1 0^{- 2})

0.00000392

Solution steps

(1.4 \cdot 1 0^{- 4}) (2.8 \cdot 1 0^{- 2})

Simplify

1.4 \cdot 1 0^{- 4} : 0.00014

= 0.00014 \cdot 2.8 \cdot 1 0^{- 2}

Apply exponent rule:

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

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

= 0.00014 \cdot 2.8 \cdot \frac{1}{1 0 ^{2}}

1 0^{2} = 100

= 0.00014 \cdot 2.8 \cdot \frac{1}{100}

Multiply the numbers:

0.00014 \cdot 2.8 = 0.000392

= 0.000392 \cdot \frac{1}{100}

= \frac{1}{100} \cdot 0.000392

\frac{1}{100} \cdot 0.000392 = \frac{0.000392}{100}

= \frac{0.000392}{100}

Divide the numbers:

\frac{0.000392}{100} = 0.00000392

= 0.00000392

89 + 7840

0.5 \cdot 0.61 \cdot 4.7 \cdot 4.7 \cdot 1 0^{- 6}

(\frac{2}{3})^{- 1}
