75=15^x

75 = 1 5^{x}

x = \frac{ln ( 75 )}{ln ( 15 )}

Decimal Notation

x = 1.59431 \dots

Solution steps

75 = 1 5^{x}

Apply exponent rules

ln (75) = x ln (15)

Solve

ln (75) = x ln (15) : x = \frac{ln ( 75 )}{ln ( 15 )}

x = \frac{ln ( 75 )}{ln ( 15 )}

2^{2 x} + 64 = 20 (2^{x})

4^{x + 1} = 2

8 (2^{2 x}) - 129 (2^{x}) + 16 = 0

2^{2 b - 3} = 32

2^{x - 4} = 7^{x}
