none of them are irrational
1.414213562 = 1,414,213,562/1000,000,000
= 707,106,781 / 500,000,000
so c) is rational
a) is not even a number
1.414213562 = 1,414,213,562/1000,000,000
= 707,106,781 / 500,000,000
so c) is rational
a) is not even a number
@Reiny they meant the square root of 25
2 years late but anything that has the square root is irrational so square root 25 is the answer so a
25 is a rational number, I think it’s C because an irrational number doesn’t have a digital pattern. 1/15 is a rational number too so now it’s just -31 and 1.414213562.. The given number cannot be considered a rational number since its decimals are not terminating.. So it’s C
