Identify Base: In log4(8), 4 is the base.Rewrite 8 as a power of 2 because 2 is a factor of 4.8=2×2×28=23
Express as Powers of 2: Now, express 4 as a power of 2 because 4 is a perfect square.4=2×24=22
Substitute into Logarithm: Substitute the expressions from Step 1 and Step 2 into the original logarithm. log4(8) becomes log(22)(23).
Apply Logarithm Power Rule: Apply the logarithm power rule, which states that logb(ac)=c⋅logb(a). log22(23) becomes 3⋅log22(2).
Simplify Logarithm Bases: Since the base of the logarithm (22) and the base of the argument (2) are the same, the logarithm simplifies to the exponent of the argument.log22(2) is 1 because any number to the power of 1 is itself.So, 3×log22(2) becomes 3×1.
Final Calculation: Multiply to find the final answer. 3×1 equals 3.
