Answer:
log(128) = t·log(2)
Step-by-step explanation:
You can take logarithms the way the formula is, or you can simplify it first.
<u>As is</u>
log(10000) = log(625) -log(8) +t·log(2)
__
<u>Simplified</u>
8·10000/625 = 2^t . . . . . multiply by 8/625
128 = 2^t
log(128) = t·log(2)
_____
Solution:
t = log(128)/log(2) = 7

Answer:
Answer below.
Step-by-step explanation:
1. a + 19 | 10 + (a + 9) = a + 19
10 + 9 = 19
a + 19

2. (C + 2/3) + 1/2 = C + 7/6
2/3 = 4/6
1/2 = 3/6
4/6 + 3/6 = 7/6
C + 7/6
