5^x=49

5^{x} = 49

x = \frac{2 ln ( 7 )}{ln ( 5 )}

Decimal Notation

x = 2.41812 \dots

Solution steps

5^{x} = 49

Apply exponent rules

x ln (5) = ln (49)

Solve

x ln (5) = ln (49) : x = \frac{2 ln ( 7 )}{ln ( 5 )}

x = \frac{2 ln ( 7 )}{ln ( 5 )}

x, 3 = 2^{x}

5^{x} = 38

2^{x + 3} + 10 = 42

3^{x} + 3^{3 x} = 30

(23)^{x} = 1728
