Mathematically, it can be displayed as:
is the logarithm of
to the base
, if
, in which case we write

Lets take the first example,

as

Therefore, 4 is the logarithm of 16 to base 2.
Lets take the second example,



- Logarithmic functions are basically inverse of exponents.
Here is how they are related to each other:
Logarithm → Exponent
→ 
- Logarithms are helpful in displaying large number.

If it is a square then find the square root of 400. Which would get you 20. So 20 is the length of one side since it is a square you multiply 20 by 4 to get 80. The perimeter is 80 feet
Answer:
3x² - 6
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 2x² + 1 + x² - 7 ← collect like terms
= 3x² - 6
