Question

log2 3+log2 a= log2 10

a. 0.3
b. 20
c. 7
d. 3.3333

Answer 1

Remember that when you add logs of the same base, you multiply what's in the log.
Since both these logs have base a, it's the same as saying that:
log2(3a) = log2(10)
Cancel out the logs to get:
3a = 10
Divide both sides to get:
a = 10/3
