5^x+5^{x+1}+5^{x+2}=155

5^{x} + 5^{x + 1} + 5^{x + 2} = 155

x = 1

Solution steps

5^{x} + 5^{x + 1} + 5^{x + 2} = 155

Factor

5^{x} + 5^{x + 1} + 5^{x + 2} : 31 \cdot 5^{x}

31 \cdot 5^{x} = 155

Divide both sides by

31

5^{x} = 5

Apply exponent rules

x = 1

e^{x} + e^{- x} = 7.4533

x^{x} = 625

t, a = p e^{r t}

2^{3^{x - 5}} = 8^{9^{x + 4}}

64 = 4^{a}
