Q. Solve for the exact value of x.5ln(5x−10)−14=−4Answer:
Isolate natural logarithm term: Isolate the natural logarithm term.We start by adding 14 to both sides of the equation to isolate the term with the natural logarithm.5ln(5x−10)−14+14=−4+145ln(5x−10)=10
Divide sides solve natural logarithm: Divide both sides by 5 to solve for the natural logarithm of (5x−10).55ln(5x−10)=510ln(5x−10)=2
Exponentiate to remove logarithm: Exponentiate both sides to remove the natural logarithm.eln(5x−10)=e25x−10=e2
Add 10 solve for 5x: Add 10 to both sides to solve for 5x.5x−10+10=e2+105x=e2+10
Divide sides solve for x: Divide both sides by 5 to solve for x.55x=5e2+10x=5e2+10
