12=10e^{0.01t}

解答

12 = 10 e^{0.01 t}

解答

t = \frac{ln ( \frac{6}{5} )}{0.01}

+1

十进制

t = 18.23215 \dots

求解步骤

12 = 10 e^{0.01 t}

交换两边

10 e^{0.01 t} = 12

两边除以

10

e^{0.01 t} = \frac{6}{5}

使用指数运算法则

0.01 t = ln (\frac{6}{5})

解

0.01 t = ln (\frac{6}{5}) : t = \frac{ln ( \frac{6}{5} )}{0.01}

t = \frac{ln ( \frac{6}{5} )}{0.01}

2.5^{3x+2}=0.4^{1-2x}

2. 5^{3 x + 2} = 0. 4^{1 - 2 x}

4^{2x-3}+16^{x-1}= 5/64

4^{2 x - 3} + 1 6^{x - 1} = \frac{5}{64}

5^{2x}-26(5^x)+25=0

5^{2 x} - 26 (5^{x}) + 25 = 0

2(3^{2x})+3^x-15=0

2 (3^{2 x}) + 3^{x} - 15 = 0

7^{3x}=49^{x+3}

7^{3 x} = 4 9^{x + 3}
