Answer 1

Answer:

6000

Step-by-step explanation:

GIVEN

${80}^{2} - {20}^{2}$

We know the formula

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

so

${80}^{2} - {20}^{2}$

can be written as

$(80 + 20)(80 - 20)$

$(100)(60)$

$= 6000$

THEREFORE YOUR ANSWER IS 6000.

I hope you are satisfied by my answer.
