Question

Write the squares of the following numbers:
(1) 75² = ...........
(2) 65² = ...........
(3) 85² = ...........
(4) 105² = ...........

Answer 1

$1){75}^{2} = 5625 \\ 2) {65}^{2} = 4225 \\ 3) {85}^{2} = 7225 \\ 4) {105}^{2} = 11025$

Answer 2

Step-by-step explanation;-

In this question

Perfect square is a product of some integer with itself.

We need to find the Squares of the following numbers.

(1) $(75)^{2}\ =\ 75\times 75\ =\ 5625$. Hence it is a perfect square.

(2) $(65)^{2}\ =\ 65\times 65\ =\ 4225$ Hence it is a perfect square.

(3) $(85)^{2}\ =\ 85\times 85\ =\ 7225$.Hence it is a perfect square.

(4)$(105)^{2}\ =\ 105\times 105\ =\ 11025$.Hence it is a perfect square

Squares of the following numbers are 5625 , 4225 , 7225 , 11025.
