Question

Perfect squares from 40 to 100?

Answer 1

Explanation:

Firstly let us write the square of 0 to 10,

• 0²=0
• 1²=1
• 2²=4
• 3²=9
• 4²=16
• 5²=25
• 6²=36
• 7²=49
• 8²=64
• 9²=81
• 10²=100

Hence,

49, 64, 81 and 100 are perfect squares from 40 to 100.

Answer 2

`\\ \tt\longmapsto 49=(7)^2`

`\\ \tt\longmapsto 64=(8)^2`

`\\ \tt\longmapsto 81=(9)^2`

• 100 won't be counted
