Answer 1

Answer:

plz follow me

Step-by-step explanation:

Step 1 :

Separate the digits by taking commas from right to left once in two digits.

18, 25

When we do so, we get 18 before the comma.

Step 2 :

Now we have to multiply a number by itself such that the product ≤ 18

(The product must be greatest and also less than 18)

Answer 2

Answer:

24

Step-by-step explanation:

we know that 35 square is 1225

this is less than 1272

so next number is 36

36 square is 1296

1296 - 1272

24
