Answer 2

Answer:

85

Step-by-step explanation:

3√7225=85

you can answer this question through tough estimation .

We will divide 7225 into groups having 3 digit each starting from left

hence 225 will be one pair and 7 another. it doesn't matter if there is one digit in a group if it's on left side like we have 7 here.

so we had 2 groups 7 and 225

see the last number or ones digit in 225 which is 5 . so the last number of the cube root will be 5 (there is a trick to find the last number of a cube )

now with second pair 7

1^3 <7<2^3

since 7 is closer to 8 than 1 the tens digit of the cube root will be 8
