10^x=2772

解答

1 0^{x} = 2772

x = \frac{ln ( 2772 )}{ln ( 10 )}

十进制

x = 3.44279 \dots

求解步骤

1 0^{x} = 2772

使用指数运算法则

x ln (10) = ln (2772)

解

x ln (10) = ln (2772) : x = \frac{ln ( 2772 )}{ln ( 10 )}

x = \frac{ln ( 2772 )}{ln ( 10 )}

so l v e f or x, h = e^{x}

2^{4 x} = 9

so l v e f or t, x = e^{t} - 9

4^{2 - n} = \frac{1}{2048}

3^{6 - x} = 2 7^{x - 2}
