Question

Ahmed thinks: "√16 = 4 so √160 = 40" he is incorrect.

Answer 1

Answer:

The square root of 160 is between 12 and 13 because 12x12=144 but 13x13=169. 160 is on between these so it must be between 12 and 13.

40 is a square root of 1600 because the equation looks like this:

40x40 It has 2 zeros, so the answer also has 2 zeros. Hence why it is 1600 not 160.
