Step-by-step explanation:
a) √ 8/10
= to get the bench mark we have to look for perfect square that are closer to the numbers 8 and 10
= for 8, it is 9 ; for 10 it is also 9
Therefore, √ 8/10 is about√ 9/9
= 3/3 = 1
b) √17/5
= to get the bench mark we have to look for perfect square that are closer to the numbers 17 and 5
= for 17, it is 16; for 5 it is 4
Therefore, √ 17/5 is about √ 16/4
= 4/2= 2
c) √7/13
= to get the bench mark we have to look for perfect square that are closer to the numbers 7 and 13
= for 7, it is 9; for 13 it is 16
Therefore, √ 7/13 is about √ 9/16
= 3/4
d) √29/6
= to get the bench mark we have to look for perfect square that are closer to the numbers 29 and 6
= for 29, it is 25; for 6 it is 4
Therefore, √ 29/6 is about √ 25/4
= 5/4
