Expand the Logarithmic Expression log base 2 of 8
Problem
Solution
Identify the base and the argument of the logarithmic expression. The base is
2 and the argument is8 Rewrite the argument as a power of the base. Since
2×2×2=8 we can express8 as2 Substitute the power back into the expression to get
(log_2)(2) Apply the power rule for logarithms, which states
(log_b)(xp)=p*(log_b)(x) Simplify the resulting expression using the identity
(log_b)(b)=1
