Question

can you solve this problem ​

Answer 1

Answer:

(205)²-(195)²

by a²-b² = (a+b)(a-b)

(205)²-(195)²

= (205+195)(205-195)

= (400)(10)

= 4000

so answer is 4000

Answer 2

Answer:

4000

Step-by-step explanation:

a= 205 , b=195

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

$205^{2} - 195^{2}$ = (205+195)(205-195)

$205^{2} - 195^{2}$=(400)(10)

$205^{2} - 195^{2}$=4000
