Question

Find the smallest number, by which 245 should be multiplied so as to get a perfect square. Also find the square root of the square number so obtained.

Answer 1

Answer:

5, 35

Step-by-step explanation:

let the no. be x,

therefore, 245x is a perfect square

on taking square roots we get,

√(245x) = 7√(5x)

so if the no is a perfect square,

7√(5x) should be rational

i.e. √(5x) should be rational

therefore x=5

hence the no formed is 245×5 = 1225

square root = √(1225)=35
