10^x=20

1 0^{x} = 20

x = \frac{ln ( 20 )}{ln ( 10 )}

Decimal Notation

x = 1.30102 \dots

Solution steps

1 0^{x} = 20

Apply exponent rules

x ln (10) = ln (20)

Solve

x ln (10) = ln (20) : x = \frac{ln ( 20 )}{ln ( 10 )}

x = \frac{ln ( 20 )}{ln ( 10 )}

1 0^{x} = 15

x, e^{\frac{x}{y}} = x - y

2 7^{x + 1} = 9

2 ln (5 - e^{- 2 x}) = 1

27 = 3^{x}
