1 0^{x} = 7.21

x = \frac{ln ( 7.21 )}{ln ( 10 )}

Decimal Notation

x = 0.85793 \dots

Solution steps

1 0^{x} = 7.21

Apply exponent rules

x ln (10) = ln (7.21)

Solve

x ln (10) = ln (7.21) : x = \frac{ln ( 7.21 )}{ln ( 10 )}

x = \frac{ln ( 7.21 )}{ln ( 10 )}

20000 = 10000 (1 + 0.15)^{t}

5 \cdot e^{- 7 x} = 12

e^{5 x} = 3

6^{x^{2} - 2 x - 24} = 1

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