The answer is The second choice (B)
Answer:
2866
Step-by-step explanation:
10000-7134=2866
so 7134+2866=10000
No it's longer because 1.29 is bigger
Answer:
![log_{100}20 = 0.6505](https://tex.z-dn.net/?f=log_%7B100%7D20%20%3D%200.6505)
Step-by-step explanation:
log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)
This basically means:
(This is the log in exponential form)
Since we don't know what
is equal to, we will say
= x
So to solve for
= x, you do the same thing. (convert to exponential form)
![100^{x} =20](https://tex.z-dn.net/?f=100%5E%7Bx%7D%20%3D20)
Now you will notice that both of these equations are equal to 20.
Since 20 = 20,
we can say
= ![10^{1.301}](https://tex.z-dn.net/?f=10%5E%7B1.301%7D)
Another way of saying 100, is
(make the bases the same)
Now we get
(we get 2x because an exponent to the power of an exponent (
) is the same as 2 * x)
Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:
2x = 1.301
x = 0.6505
