Question

if the sum of squares of two numbers is 97 then which of the following cannot be their product?

1. 64
2. -32
3. 16
4. 48

Answer 1

Answer:

Step-by-step explanation:

We first list down the possible squares.

The squares are of numbers from 1 to 9

They include :

1, 4, 9, 16, 25, 36, 49, 64, 81, 100

The two squares that can give us 97 when added are :

81 and 16

81 + 16 = 97

And the numbers are 4 and 9

The 16, 48 and 64 are multiples of 4.

However - 32 is not a positive multiple of 4.

Hence it is the odd one out.
