What is the simplest form of the radical expression ���2 ���5/���2-���5 ? ?

(√2 + √5) / (√2 - √5) =
(√2 + √5) * (√2 - √5) / (√2 - √5) * (√2 - √5) =
(√2² - √5²) / (√2 - √5)² =
(2 - 5) / (√2² - 2√10+ √5²) =
-3 / (2 - 2√10 + 5) =
-3 / (7 - 2√10)

or

(√2 + √5) / (√2 - √5) =
(√2 + √5) * (√2 + √5) / (√2 - √5) * (√2 + √5) =
(√2 + √5)² / (√2² - √5²) =
(√2² + 2√10+ √5²) / (2 - 5) =
(2 + 2√10 + 5) / -3 =
- (7 + 2√10) / 3

P(Spinner lands on purple section) = 0.6 = 60%

Step-by-step explanation:

We are given the following in the question:

Number of sections = 10

Number of purple sections = 6

a) probability that the spinner will land on purple purple

P(purple) =

0.6 is the probability that the spinner will land on purple purple.

b) Interpretation of probability

There is a 60% chance that the spinner will land on purple color.
