Question: Solve Exponential Equation: 2(x-5)=17x
You can show exponential quantitites using a normal qwerty keyboard with the carat symbol '^'.
Any exponent with two characters or more should be bracketed.
Your exponential equation then is: 2^(x-5) = 17^x
Taking logs of both sides,
ln[2^(x-5)] = ln[17^x]
(x-5).ln[2] = x.ln[17]
x.ln[2] - 5.ln[2] = x.ln[17
x{ln[2] - ln[17]} = 5.ln[2] = ln[32]
x{ln[2/17]} = ln[32]
x = ln[32] / ln[2/17] = 3.46573 / (-2.14007) = - 1.61945
x = - 1.61945
