Question

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.

e^Inx^2 - 9 = 0

Answer 1

x=3 , x=-3

Explanation:

`e^(lnx^2) -9= 0`

Add 9 on both sides

`e^(lnx^2)=9`

To remove base 'e' we take ln on both sides

`ln e^(lnx^2)=ln9`

`lnx^2=ln(9)`

Both sides have ln , so we make the terms equal

`x^2=9`

Take square root on both sides

`x=+-3`

x=3 , x=-3
