Answer:
Step-by-step explanation:
Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.
17^x = 2 Take the log of both sides
log(17^x) = log(2) Take the x outside the brackets
x log(17) = log(2) Divide by log 17
x = log(2)/log(17) Find the values for log 2 and log 17
log(2) = 0.3010
log(17) = 1.230
x = .3010/1.230
x = .2446
A. 11w=88
11w/11=88/11
w=8
b. 7u=210
7u/7=210/7
u=30
c. v÷81=9
v/81×81=9×81
v=729
d. c÷4=16
c/4×4=16×4
c=64

11b+7=40
Subtract 7 from both sides.
11b+7−7=40−7
11b=33
Divide both sides by 11.
11b/11 = 33/11
b=3
