solvefor x,9^x= 1/3

解答

求解

x, 9^{x} = \frac{1}{3}

x = - \frac{1}{2}

十进制

x = - 0.5

求解步骤

9^{x} = \frac{1}{3}

使用指数运算法则

2 x = - 1

解

2 x = - 1 : x = - \frac{1}{2}

x = - \frac{1}{2}

so l v e f or x, \frac{2}{5} = \frac{6}{x} - 2

so l v e f or x, \frac{1}{3} x = 6

s im pl i f y \frac{- 56}{65}

j o in r + (- 5 r)

s im pl i f y (\frac{1}{( x ^{3} )})^{2}
