For this case we must find the value of the variable "x" of the following expression:


4(10^(5x))=200

We divide both sides of the equation by 4:


10 ^ {5x} = \frac {200} {4}\\10 ^ {5x} = 50

We find ln on both sides of the equation to remove the exponent variable:


ln (10^(5x)) = ln (50)\\5x * ln (10) = ln (50)

We divide both sides of the equation between 5 * ln (10):
x = \frac {ln (50)} {5 * ln (10)}

In decimal form we have:


x = 0.33979400

ANswer:


x = 0.33979400
