Final answer:
To find the value of u.log3(u) = 4, rewrite the equation as 3^(4/u) = u and solve for u.
Step-by-step explanation:
To find the value of u.log3(u) = 4, we need to solve for u.
Using logarithm rules, we can rewrite the equation as log3(u) = 4 / u. Since the base of the logarithm is 3, we want to find the value of u that satisfies this equation.
To solve for u, we can rewrite the equation as 3^(4/u) = u. Now we can use trial and error or graphing methods to find the value of u that satisfies the equation.
