2^r=100

2^{r} = 100

r = \frac{2 ln ( 10 )}{ln ( 2 )}

Decimal Notation

r = 6.64385 \dots

Solution steps

2^{r} = 100

Apply exponent rules

r ln (2) = ln (100)

Solve

r ln (2) = ln (100) : r = \frac{2 ln ( 10 )}{ln ( 2 )}

r = \frac{2 ln ( 10 )}{ln ( 2 )}

3^{x + 1} = 7

2^{4} \cdot (0.5)^{- 3} = 2^{k}

e^{x} \cdot (x - 1) = 0

7^{3 - 5 x} = 1

1 + e^{- x} = 0
