4 (10)^{x} = 20

x = \frac{ln ( 5 )}{ln ( 10 )}

Solution steps

4 (10)^{x} = 20

Divide both sides by

4

1 0^{x} = 5

Apply exponent rules

x ln (10) = ln (5)

Solve

x ln (10) = ln (5) : x = \frac{ln ( 5 )}{ln ( 10 )}

x = \frac{ln ( 5 )}{ln ( 10 )}

2 e^{2 x + 7} - 15 = 0

e^{3 x} = 4

6^{x - 2} = 36

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

1 0^{1 - x} = \frac{1}{10}
