1 5^{x + 3} = 18

x = \frac{ln ( 18 )}{ln ( 15 )} - 3

Decimal Notation

x = - 1.93267 \dots

Solution steps

1 5^{x + 3} = 18

Apply exponent rules

(x + 3) ln (15) = ln (18)

Solve

(x + 3) ln (15) = ln (18) : x = \frac{ln ( 18 )}{ln ( 15 )} - 3

x = \frac{ln ( 18 )}{ln ( 15 )} - 3

2^{2 (x + 1)} + 3 (2^{x}) = 1

3^{2 x} = 2 7^{x - 1}

e^{x + 2} = 6

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

x, 4 - (6^{5 - 3 x}) = - 5
