(In y)^3=7 In y

Question

Help me please

Answer 1

Divide both sides of equation by (ln y).

 

(ln y)² = 7

 

 

Square-root both sides of equation.

 

ln y = √(7)

 

Now, we have a natural log equation that is easier to deal with.

 

The solution to a natural log is the exponent of the base number e.

 

e^√(7) = y

 

14.094 = y
