Answer:
7k^6
Step-by-step explanation:
The value is ten times the value.
You break it up by taking the numbers by itself.
In the first number it's 500.
In the second it's 50.
From there you need to just figure out how the place value is different.
In this case it's different time 10.

Question:
Approximate log base b of x, log_b(x).
Of course x can't be negative, and b > 1.
Answer:
f(x) = (-1/x + 1) / (-1/b + 1)
Step-by-step explanation:
log(1) is zero for any base.
log is strictly increasing.
log_b(b) = 1
As x descends to zero, log(x) diverges to -infinity
Graph of f(x) = (-1/x + 1)/a is reminiscent of log(x), with f(1) = 0.
Find a such that f(b) = 1
1 = f(b) = (-1/b + 1)/a
a = (-1/b + 1)
Substitute for a:
f(x) = (-1/x + 1) / (-1/b + 1)
f(1) = 0
f(b) = (-1/b + 1) / (-1/b + 1) = 1
7 times 7 = 49. Perfect square.
3 times 3 = 9. Perfect square.
15 times 15 = 225. Again, a perfect square.
The other two, 17 and 143, come out as decimals. So, your final answer would be 49, 7 and 225. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)
