Answer:
The answer to your question is 64b³ - 48b²k + 36bk² - 27k³
Step-by-step explanation:
(4b - 3k)³
To solve this problem, use Newton's binomial theorem
For a binomial to the third power = 1 3 3 1
(4b)³ + (4b)²(-3k) + (4b)(-3k)² + (-3k)³
Simplification
64b³ + (16b²)(-3k) + (4b)(9k²) - 27k³
Result
64b³ - 48b²k + 36bk² - 27k³
For the denominator of 12, Your fractions will now look like:
8/12 ( Simplify if needed) as well as
9/12 (Simplify if needed)
You want to find the multiple that will give you 12 upon the bottom of the fraction and divide your numerator by that number as well. For the first one, it’s 3, and for the second one, it’s 6
Add 75 and 15 then minus 64. Add 70 and 80 then add the answers
