The boy will be 34 inches. You divide 68 divided by 2 which = to 34 inches
A:1.23
E: note that 125= 5^3 thus, log_b (125) = log_b(5^3) we can now simplify using the rule log_b(a^c) = c • log_b (a) log_b (5^3) = 3 • log_b (5) since log_b (5) = 0.41, we know that 3 • log_b (5) = 3•0.41 = 1.23
Glad to help :D
