Question

Between which two consecutive integers does √53 lie?

Answer 1

Hey there :)

We can solve 2 ways: With a calculator and Without

With:
√53 = 7.28

Therefore this lies between 7 and 8

Without:
6² and 7² = 36 and 49
Still, the values are less than 53, which means √53 does not lie between 6 and 7

7² and 8² = 49 and 64
53 is between both values, therefore √53 lies between 7 and 8

Your answer will be option B) 7 and 8
