Answer:
125
Step-by-step explanation:
log2 (24) - log2 (3) = log5 (x)
We know that log a(b) - log a(c) = log a( b/c)
log2 (24/3) = log5 (x)
log2 (8) = log5 (x)
Rewriting 8 as 2^3
log2 (2^3) = log5 (x)
We know that log a ( a^b) = b loga (a) and loga (a) =1
3 log2 (2) = log5 (x)
3 *1 = log5 (x)
3 = log5 (x)
We know log a (b) =c can be written as a^c =b
5^3 = x
125 =x
Answer:
Step-by-step explanation: 40 and 24 are 5:3. We know his because:
- 40/8=5
- 24/8=3
That's how we know 40:24 = 5:3.
