-4+4e^{(8x+2.5)}=84

Solution

- 4 + 4 e^{(8 x + 2.5)} = 84

Solution

x = \frac{ln ( 22 ) - 2.5}{8}

+1

Decimal Notation

x = 0.07388 \dots

Solution steps

- 4 + 4 e^{(8 x + 2.5)} = 84

Move

4

to the right side

4 e^{8 x + 2.5} = 88

Divide both sides by

4

e^{8 x + 2.5} = 22

Apply exponent rules

8 x + 2.5 = ln (22)

Solve

8 x + 2.5 = ln (22) : x = \frac{ln ( 22 ) - 2.5}{8}

x = \frac{ln ( 22 ) - 2.5}{8}

Popular Examples

e^{x^{2}} = 3

3^{x} = 9^{2 x - 1}

3^{7 x} = 3.3

\frac{1}{3} \cdot 2^{x} = 12

3^{x+1}-4+1/(3^x)=0

3^{x + 1} - 4 + \frac{1}{3 ^{x}} = 0
