7^{9 x + 7} = 2

x = \frac{ln ( 2 ) - 7 ln ( 7 )}{9 ln ( 7 )}

Decimal Notation

x = - 0.73819 \dots

Solution steps

7^{9 x + 7} = 2

Apply exponent rules

(9 x + 7) ln (7) = ln (2)

Solve

(9 x + 7) ln (7) = ln (2) : x = \frac{ln ( 2 ) - 7 ln ( 7 )}{9 ln ( 7 )}

x = \frac{ln ( 2 ) - 7 ln ( 7 )}{9 ln ( 7 )}

x, y = 3^{x}

x, 7^{x - 1} = e^{y}

5^{2 x - 3} = 7^{x + 1}

21 6^{x + 2} = 7776

4^{x} + 5 = 8
