Answer:
Step-by-step explanation:
When dividing fractions, you just need to remember that all you need to do is get the inverse of the divisor and multipy.
So for the problem
5 = divident
3/4 = divisor
So we get the inverse of 3/4 which is 4/3 and then multiply.
Look above to see the process.
5 + 2 = 7
84/7 = 12
12 x 5 = 60
12 x 2 = 24
Answer is 60:24
Answer:
To answer your question: Rewrite 81x2 as (9x)2.(9x)2−49Rewrite 49 as 72.(9x)2−72 Both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=9x and b=7.(9x+7)(9x−7)
If you want your answer in Scientific Notation it would be 4.5*10^11
