What is this ???????????????
Answer:
5 -2√10 = C
Step-by-step explanation:
√25 -√40
√25 = √5 x5 = √5² = 5
√40 = √5 x 8 = √5x 2x4 = √10x4 = √10x 2² = 2√10 (when the 2 comes back into the square root it become 2²)
√25 -√40 = 5 -2√10
More flour cause you put the fractions over the same denominator and change to an improper fraction to get 2 3/4 = 11/4 and 2 1/2 = 5/2 = 10/4 and 11/4 is greater than 10/4.
