8^{x+3}=32^{3x}

8^{x + 3} = 3 2^{3 x}

x = \frac{3}{4}

Decimal Notation

x = 0.75

Solution steps

8^{x + 3} = 3 2^{3 x}

Apply exponent rules

3 (x + 3) = 15 x

Solve

3 (x + 3) = 15 x : x = \frac{3}{4}

x = \frac{3}{4}

7^{z^{2} + 4} = 7^{- 4 z}

x^{x} = 31

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

e^{3 x} = \frac{1}{8}

3 (4^{x}) = (2)^{3 x - 5}
