Answer:
To solve this you must first know how Log works.
When we say log1000 of base 10
Or
log1000=3
What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).
So log2x=−5 (i am assuming base 10 since it is simple algebra) means that
2x=10−5
x=10−5/2
Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.
The question is not written properly, so I will give the answer(s) I think would be suitable.
If you were trying to solve this
log2x=−5
⟹x=2−5
⟹x=132
But if you were trying to solve this
log2x=−5
⟹log102x=−5
⟹2x=10−5
⟹x=12×105=1200000

Answer:
Step-by-step explanation:
1 inch to 12 ft = x inches to 75 ft
1 / 12 = x / 75
cross multiply
12x = 75
x = 75/12
x = 6.25 or 6 1/4 inches
1 inch to 12 ft = x inches to 80 ft
1 / 12 = x / 80
cross multiply
12x = 80
x = 80/12
x = 6.67 or 6 2/3 inches
so the dimensions are : 6 1/4 inches by 6 2/3 inches <====
