Answer:
Convert into same base
Step-by-step explanation:
Convert both sides into same bases and equate the powers to solve for the variable.
Example:
8^x = 32
You can either use logs to bring the power down or convert both sides into the same base
8 = 2³
8^x = (2³)^x = 2^(3x)
32 = 2⁵
2^(3x) = 2⁵
3x = 5
x = 5/3
x = 1⅔
Answer:
White Gold.
Step-by-step explanation:
This type of gold contains only 75% pure gold, not 100%.
The domain of this equation is the lowest x value to the highest x value. For example: lowest is -4 and highest is 3. You would write it as [-4,3]
For this equation, the domain is (-infinity,infinity) because there is no lowest or highest x value.
Answer:
and
Step-by-step explanation:
First make all the fractions into improper fractions
After doing that put them back into the problems
Problem 1)
÷ 
, plug in the improper fractions
÷ 
to divide, you need to flip the second fraction and multiply
· 
= 
then reduce
Problem 2)
÷ 
Plug in improper fraction
÷
Then flip second fraction and multiply
· 
Multiply
Reduce, or make it a mixed number
