Question

How many numbers lie between squares of the following numbers? (i) 12 and 13
​

Answer 1

Answer:

24 numbers

Step-by-step explanation:

Method 1:

Let us consider the square of the given two numbers

122 = 12 × 12

122 = 144

132 = 13 × 13

132 = 169

Numbers lies between 169 and 144 are

145,146,147,148,149, 150,151,152,153,154,155,156,157,158,159,160,161,162,163,164,165,166,167,168.

∴ Total 24 numbers lies between 144 and 169.

Method 2:

12 square=144

13 square=169

169−144=25

So, there are 25−1=24 numbers lying between 12 and 13

So, there are 25−1=24 numbers lying between 12 and 13
