3^{3 x + 4} = 21

x = \frac{ln ( \frac{7}{27} )}{3 ln ( 3 )}

Decimal Notation

x = - 0.40958 \dots

Solution steps

3^{3 x + 4} = 21

Apply exponent rules

(3 x + 4) ln (3) = ln (21)

Solve

(3 x + 4) ln (3) = ln (21) : x = \frac{ln ( \frac{7}{27} )}{3 ln ( 3 )}

x = \frac{ln ( \frac{7}{27} )}{3 ln ( 3 )}

3^{3 x + 4} = 12

x, 2^{x} = 32

1 7^{x + 2} = 4

384 e^{8} = 2^{x}

3^{- 8 x} = 9^{3 - 3 x}
