Cannot give you 10 examples dear but can help you with the first part of the question
√70
first,try to guess the square root
√70 = 8(8 × 8 = 64)
Now divide the no. by your approx answer
70÷8=8.85
Then, split the difference between your estimate
the difference equals: 8.75 - 8 = 0.75
splitting the difference (dividing by 2) we get:
0.75÷2=0.375
finally, add this result to the original estimate 8;
8 + 0.375 = 8.375
The answer will be slightly high so round it off downwards.
Need further help message me
-regards
