Step-by-step explanation:
Logarithm is basically the exponent - also called power - to which a base must be raised to produce a given number.
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.
Answer:
Step-by-step explanation:
They are both technically right 7 time 9 is 63 but 7 time 9 is equivalent to 9 times 7
Answer:
360 miles
Step-by-step explanation:
Answer:
We need to find a relationship between the equations.
Let's solve for one variable.
2x + 2y = 15
2y = 15 - 2x
We know what 2y is in relation to x. Now we can solve.
2x + 15-2x = 15
15 = 15
Unless there are more equations, this is your answer. For it to be simultaneous you need more than one equation.
