Value of x = 7.499
Step-by-step explanation:
We need to find value of x in the equation:
This can be solved using natural log
Solving:
Subtract 7 from both sides:
Simplifying:
Using rule if f(x)=g(x) then, ln(f(x))=ln(g(x))
So,
Applying log rule: logₐ(x^b)= b logₐ(x)
Divide both sides by 2ln(2)
So, Value of x = 7.499
