Answer:
(a) √25 rational
(b) √30 irrational
Step-by-step explanation:
Note : only perfect squares have rational roots
25 = 5² then 25 is a perfect square
therefore √25 = 5 is a rational number
30 cannot be written in the form a² where ‘a’ I start a natural number then 30 is not a perfect square
Therefore √30 is irrational.
Answer:
31.62
Step-by-step explanation:
If we know it's a right triangle, we can use the Pythagorean Theorem to solve this problem.
10^2 + 30^2 = 1000
Find the square root of 1000 and get your answer of 31.62.
Hope this Helps!
Good Luck!
