Question

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

In 4x = 1

Answer 1

`x=(e)/(4)`

Explanation:

`ln(4x)=1`

for log the base of log is 10 and for natural log ln has base 'e'

To solve for x , convert the log form in to exponential form

Natural log ln has base 'e'

`ln_e(4x)=1`

`(4x)=e^1`

`4x=e`

divide both sides by 4

`x=(e)/(4)`
