2^{2 x + 3} = 15

x = \frac{ln ( 15 ) - 3 ln ( 2 )}{2 ln ( 2 )}

Decimal Notation

x = 0.45344 \dots

Solution steps

2^{2 x + 3} = 15

Apply exponent rules

(2 x + 3) ln (2) = ln (15)

Solve

(2 x + 3) ln (2) = ln (15) : x = \frac{ln ( 15 ) - 3 ln ( 2 )}{2 ln ( 2 )}

x = \frac{ln ( 15 ) - 3 ln ( 2 )}{2 ln ( 2 )}

3^{x} + 3^{x + 1} = 4

e^{x} = e^{2 x}

3 = e^{x - 3}

e^{y} = e

\frac{3000}{2 + e ^{2 x}} = 2
