Solution steps

2. 5^{x} + 4 = 1254

Move

4

to the right side

2. 5^{x} = 1250

Apply exponent rules

x ln (2.5) = ln (1250)

Solve

x ln (2.5) = ln (1250) : x = \frac{ln ( 1250 )}{ln ( 2.5 )}

x = \frac{ln ( 1250 )}{ln ( 2.5 )}

2^{x} - 2 \cdot 4^{x} = 0

e^{- 4 x} = 0

291 6^{x} = 54

3^{x} + 3^{x + 2} = 81

1 0^{x} = 12
