7^{x + 2} = 3

x = \frac{ln ( 3 )}{ln ( 7 )} - 2

Decimal Notation

x = - 1.43542 \dots

Solution steps

7^{x + 2} = 3

Apply exponent rules

(x + 2) ln (7) = ln (3)

Solve

(x + 2) ln (7) = ln (3) : x = \frac{ln ( 3 )}{ln ( 7 )} - 2

x = \frac{ln ( 3 )}{ln ( 7 )} - 2

(\frac{1}{12})^{x - 2} = 2^{4 \cdot x} \cdot 3^{2 \cdot x}

2 \cdot 3^{x + 1} + 3^{x + 3} = 33

x, 2^{x + 1} - 1 = 7^{y}

2^{4 x + 3} = 8^{x - 5}

5^{2 x + 1} = 3^{4 x - 1}
