10^{-7.52}=(x^2)/(10^{-3)}

解答

1 0^{- 7.52} = \frac{x ^{2}}{1 0 ^{- 3}}

解答

x = \frac{1}{50 1 0 ^{13} \cdot 100000}, x = - \frac{1}{50 1 0 ^{13} \cdot 100000}

+1

十进制

x = 5.49541 E - 6, x = - 5.49541 E - 6

求解步骤

1 0^{- 7.52} = \frac{x ^{2}}{1 0 ^{- 3}}

交换两边

\frac{x ^{2}}{1 0 ^{- 3}} = 1 0^{- 7.52}

化简

1 0^{- 7.52} : \frac{1}{1 0 ^{7.52}}

\frac{x ^{2}}{1 0 ^{- 3}} = \frac{1}{1 0 ^{7.52}}

在两边乘以

1 0^{- 3}

x^{2} = \frac{1}{1 0 ^{10.52}}

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = \frac{1}{1 0 ^{10.52}}, x = - \frac{1}{1 0 ^{10.52}}

\frac{1}{1 0 ^{10.52}} = \frac{1}{50 1 0 ^{13} \cdot 100000}

- \frac{1}{1 0 ^{10.52}} = - \frac{1}{50 1 0 ^{13} \cdot 100000}

x = \frac{1}{50 1 0 ^{13} \cdot 100000}, x = - \frac{1}{50 1 0 ^{13} \cdot 100000}
