2^n=20

2^{n} = 20

n = \frac{ln ( 20 )}{ln ( 2 )}

Decimal Notation

n = 4.32192 \dots

Solution steps

2^{n} = 20

Apply exponent rules

n ln (2) = ln (20)

Solve

n ln (2) = ln (20) : n = \frac{ln ( 20 )}{ln ( 2 )}

n = \frac{ln ( 20 )}{ln ( 2 )}

x, 2^{x - 1} = 31

4^{x} - 2^{x + 3} + 12 = 0

2^{x + 3} - 2^{x} = 56

a^{x} = 2

4 e^{3 x - 2} = 8
