Question

Slove this (79)2 - (69)2​

Answer 1

Answer:–

(79)² - (69)² = 1480

_______________________

Explanation:–

Let us simplify the given expression using the formula

(a – b) (a + b) = a² – b²

So,

(79)² – (69)²

= (79 + 69) (79 – 69)

= (148) (10)

= 1480

Therefore, (79)² - (69)² = 1480

Answer 2

Answer:

$(79)^{2} - (69)^{2}$

$ID=> (a+b) (a-b) = (a)^{2} - (b)^{2}$

= (79 + 69) (79 - 69)

= (148) (10)

= 1480
