I'll give brainliest if you show your work. plz answer quickly. nolan used the following procedure to find an estimate for the square root of 18. step 1: since 4^2=16 and 5^2= 25 and 16 < 18 < 25, the square root of 18 is between 4 and 5. 4.1^2=16.81 4.2^2=17.64 4.3^2=18.49 4.4^2=19.36 step 3: since 18.49 rounds to 18, 4.3 is the best approximation for the square root of 18. in which step, if any, did nolan make an error? a) in step 1, the square root of 18. is between 4 and 5 because the square root of 18 equals about 20 and 4 times 5= 20. b) in step 2, he made a calculation error when squaring. c) in step 3, he should have determined which square is closest to 18. d) nolan did not make an error.
