Question

Find by using suitable identity: 983(square)-17 ( square)

Answer 1

→ 983^2 - 17^2

by identity a^2 -b^2 = (a + b)(a - b)

→ (983+17) ( 983-17)

→ (1000)(966)

→966000

Answer 2

Answer:

983²-17²  = 966000

Step-by-step explanation:

Required to find,

983²-17²

Recall the formula

a²-b² = (a+b)(a-b)

Solution

By applying the formula a²-b² = (a+b)(a-b), with a = 983 and b = 17 we get

983²-17² = (983+17)(983 -17)

= 1000× 966

= 966000

983²-17²  = 966000
