Question

Solve for X. Round to the nearest hundredth. 3=ln(x+9)

Answer 1

3 = Ln (x + 9)
To clear a natural log you will add a base 'e' to both sides.
e^3 = e^(Ln(x+ 9))
Using the power rule and identity rule, the e^(Ln) = 1, and the (x + 9) becomes a coefficient.
e^3 = (x + 9) * 1
e^3 = x + 9
e^ 3 - 9 = x
11.09 = x
