b. 98
c. 117
d.287
e. 15
( do it in method)

Answer 1

5^2 has 2 digits
98^2 has 4
117^2 has 5
287^2 has 5
15^2 has 3

Answer 2

Concept

The square of the digits is the multiplication of the same number

for example if we need to find the square of digit x then we will multiply x with x that will be x^2

Given

The digits given are 5 , 98 , 117 , 287 , 15

Find

We need to find the the possible number of digits in the squares of the given digits

Solution

1. 5

To calculate the squares of the digits of 5 multiply 5 with 5

that is 5*5 = 25

Hence the square of 5 has 2 digits

2. 98

To calculate the squares of the digits of 98 multiply 98 with 98

that is 98*98 = 9604  

Hence the square of 98 has 4 digits

3. 117

To calculate the squares of the digits of 117 multiply 117with 117

that is 117*117 = 13689

Hence the square of 117 has 5 digits

4. 287

To calculate the squares of the digits of 287 multiply 287with 287

that is 287*287 = 82369

Hence the square of 287 has 5 digits

5. 15

To calculate the squares of the digits of 15 multiply 15 with 15

that is 15*15 = 225

Hence the square of 15 has 3 digits
