step 1
Find the two perfect square numbers it lies between.
Solution:
4²= 16 and 5² = 25, so lies between 4 and 5.
step 2
Divide 22 by 4. 22/4 = 5.5 (you can round off your answer)
step 3
Average 5.5 and 4. (5.5+4)/2 = 4.75
step 4
repeat step 2
Divide 22 by 4.75. 22/4.75 = 4.6316
step 5
repeat step 3
Average 4.75 and 4.6316. (4.75+4.6316)/2 = 4.6908
the answer is
4.69
