(6^{10})/(6^x)=6^6

解答

\frac{6 ^{10}}{6 ^{x}} = 6^{6}

x = 4

求解步骤

\frac{6 ^{10}}{6 ^{x}} = 6^{6}

使用指数运算法则

10 - x = 6

解

10 - x = 6 : x = 4

x = 4

验证解:

x = 4

真

解是

x = 4

1.728 = 1. 2^{x}

3^{4 - 5 x} = 2^{x + 4}

2^{5 x + 5} + 2^{5 x + 1} = 17

e^{- x} (x^{2} - 5 x + 2) = 0

so l v e f or y, 2^{x + y} = x
