Question

8. If 25 x 25 = 2 x (2 + 1) 100 + 25 = 625
35 x 35 = 3 * (3 + 1) 100 + 25 = 1225
45 x 45 = 4 * (4 + 1) 100 + 25 = 2025
Using the above pattern, write the expansion
65 x 65 =
95 x 95​

Answer 1

Solution :

→ 25 x 25 = 2 × (2 + 1) 100 + 25 = 625

→ 35 x 35 = 3 × (3 + 1) 100 + 25 = 1225

→ 45 x 45 = 4 × (4 + 1) 100 + 25 = 2025

By using the same pattern, the expression of —

→ 65 x 65 = 6 × (6 + 1) 100 + 25 = 4225

→ 95 x 95 = 9 × (9 + 1) 100 + 25 = 9025

Answer 2

Answer:

easy pasy

firstly we use same method to solve that

Step-by-step explanation:

65 *65=6*(6+1) 100+25=4225

95*95=9*(9+10) 100+25=9025

but I give you another way to slove problem

65*65= 4225

firstly after 6 which number comes 7 then 7*6

= 42,then square of 5*5=25 which write this like

4225
