It really depends on the question and what you want to solve. An exponential function can be written as y = x^2 and if you are solving for y then it will be log(base x) y = 2.
More Examples:
3x = 15
(log both sides with base of 3)
log(3)3x = log(3)15
since log(3)3 = 1 then,
(1)x = log(3)15
x = log 15 / log 3
= 2.465
Answer:
212,000
Step-by-step explanation:
212 089, better written as 212,089, rounds down to 212,000.
As an example, 212,589 would round up to 213,000, and
212,389 would round down to 212,000.
Answer:
option B
Step-by-step explanation:
To find the number which is written in the standard form,
We expand 
and multiply by 5 to get
=5000
The answer is 32.72 degree.

X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
