Question

In65 - lnX = 39
What does X=?

Answer 1

The answer is 7.47

Explanation:

In this problem we are going find the natural logarithmic of the numbers involved and solve for x

`ln65-Ln x= 39\\`

from tables

ln 65= 4.17

`4.17-ln x= 39\4.17-39= lnx\\-34.83=lnx\\`

taking the exponents of both sides we have

`e^-^3^4^.^8^3= x\\x= 7.47`
