Answer:
4 and 5
Step-by-step explanation:
For answering questions like this, it can be useful to remember a few of the powers of small integers:
2^4 = 16
2^5 = 32
<h3>Exponents and logarithms</h3>
A logarithm can be considered to be an exponent of the base.
The ordering of powers of 2 relative to the number of interest (17) is ...
16 < 17 < 32
2⁴ < 17 < 2⁵ . . . . . . . . . . . . . . . . . . . expressed as powers of 2
log₂(2⁴) < log₂(17) < log₂(2⁵) . . . . . log₂ of the above inequality
4 < log₂(17) < 5 . . . . . . . . . . . . . . . . showing the values of the logs
Log₂(17) lies between 4 and 5.

<em>Additional comment</em>
Using the "change of base" formula, you can use a calculator to find the value of log₂(17). It shows you the value is between 4 and 5.
log₂(17) = log(17)/log(2) . . . . . . using logs to the same base

Answer:
500
Step-by-step explanation:
1 divided into each runner
There is no sign in between 2b and 6.
Case 1:
Assuming the sign is '+'
Then, 2b + 6 for b = 9 is given by 2(9) + 6 = 18 + 6 = 24.
Case 2:
Assuming the sign is '-'
Then, 2b - 6 for b = 9 is given by 2(9) - 6 = 18 - 6 = 12.
Case 3:
Assuming the sign is 'x'
Then, 2b x 6 for b = 9 is given by 2(9) x 6 = 18 x 6 = 108.
Case 4:
Assuming the sign is '÷'
Then, 2b ÷ 6 for b = 9 is given by 2(9) ÷ 6 = 18 ÷ 6 = 3.
