simplify

\frac{2 1 ^{8.4}}{2 0 ^{8.4}}

1.50657 \dots

Solution steps

\frac{2 1 ^{8.4}}{2 0 ^{8.4}}

Apply exponent rule:

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

\frac{2 1 ^{8.4}}{2 0 ^{8.4}} = (\frac{21}{20})^{8.4}

= (\frac{21}{20})^{8.4}

Convert element to a decimal form

\frac{21}{20} = 1.05

= 1.0 5^{8.4}

1.0 5^{8.4} = 1.50657 \dots

= 1.50657 \dots

e^{- 3 x} \cdot e^{2 x}

(\frac{5 ( x ^{2} - 1 ) ^{3}}{3 x})^{\frac{1}{2}}

\frac{( 0.04 + 12 \cdot 1 0 ^{- 2} ) ^{3}}{( 0.02 ) ^{3}}

- e^{- 1} \cdot e^{- 1}
