(100)/(1+e^{2x)}=1

Solution

\frac{100}{1 + e ^{2 x}} = 1

Solution

x = \frac{ln ( 99 )}{2}

+1

Decimal

x = 2.29755 \dots

Solution steps

\frac{100}{1 + e ^{2 x}} = 1

Multiply both sides by

1 + e^{2 x}

\frac{100}{1 + e ^{2 x}} (1 + e^{2 x}) = 1 \cdot (1 + e^{2 x})

Simplify

100 = 1 + e^{2 x}

Switch sides

1 + e^{2 x} = 100

Move

1

to the right side

e^{2 x} = 99

Apply exponent rules

2 x = ln (99)

Solve

2 x = ln (99) : x = \frac{ln ( 99 )}{2}

x = \frac{ln ( 99 )}{2}

Verify Solutions:

x = \frac{ln ( 99 )}{2}

True

The solution is

x = \frac{ln ( 99 )}{2}
