7^{4 x} = 3 1^{3 x + 4}

x = \frac{4 ln ( 31 )}{4 ln ( 7 ) - 3 ln ( 31 )}

Decimal Notation

x = - 5.45440 \dots

Solution steps

7^{4 x} = 3 1^{3 x + 4}

Apply exponent rules

4 x ln (7) = (3 x + 4) ln (31)

Solve

4 x ln (7) = (3 x + 4) ln (31) : x = \frac{4 ln ( 31 )}{4 ln ( 7 ) - 3 ln ( 31 )}

x = \frac{4 ln ( 31 )}{4 ln ( 7 ) - 3 ln ( 31 )}

2^{x} = 162

(\frac{1}{4})^{2 x} = 3 2^{4 x - 2}

y, 2^{y} = x

3^{2 x} = 243

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