Question

Write the exact value solution and an approximation for 10^4x=25

Answer 1

exact value:
`x= (log25)/(4)`

approximate: x=0.349485

Explanation:

Exact Value:

`10^(4x) = 25`

`log (10^(4x))= log 25`

`4x = log 25`

`x= (log25)/(4)`

Approximate:

`x= (log25)/(4)`

`x=1.39794/4\\`

`x=0.349485`
