Question

EXERCISE 3B 1. Give reason to show that none of the numbers given below is a perfect square: (1) 5372 (1) 5963 (in) 8457 (iv) 9468​

Answer 1

Answer:

(i) Given 5372 By observing the property 1 of perfect square i.e. a number ending in 2 is never a perfect square.Therefore the given number 5372 is not a perfect square. (ii) Given 5963 We have the property 1 of perfect square i.e. a number ending in 3 is never a perfect square.Therefore the given number 5963 is not a perfect square. (iii) Given 8457 We have the property 1 of perfect square i.e. a number ending in 7 is never a perfect square.Therefore the given number 8457 is not a perfect square. (iv) Given 9468 We have the property 1 of perfect square i.e. a number ending in 8 is never a perfect square.Therefore the given number 9458 is not a perfect square. (v) Given 360 We know the property 2 of perfect square i.e. a number ending in an add number of zeros is never a perfect square.Therefore the given number 360 is not a perfect square. (vi) Given 64000 We know the property 2 of perfect square i.e. a number ending in an add number of zeros is never a perfect square.Therefore the given number 64000 is not a perfect square. (vii) Given 2500000 We know the property 2 of perfect square i.e. a number ending in an add number of zeros is never a perfect square.Therefore the given number 2500000 is not a perfect square.Read more on Sarthaks.com - https://www.sarthaks.com/728552/give-reason-show-that-none-of-the-numbers-given-below-is-perfect-square-5372-ii-5963-iii-8457
