Evaluate (using factors) : 301^2 x 300 - 300^3

301 2 x 300 \- 300 3 = 300 x (301 2 \- 300 2 ) Using the formula [∵ (x 2 \- y 2 ) = (x \+ y)(x \- y)] = 300 x (301 \- 300) x (301 \+ 300) = 300 x 1 x 601 = 1,80,300 Hence, 301 2 x 300 \- 300 3 = 1,80,300

Answer

301² x 300 - 300³

= 300 x (301² - 300²)

Using the formula

[∵ (x² - y²) = (x + y)(x - y)]

= 300 x (301 - 300) x (301 + 300)

= 300 x 1 x 601

= 1,80,300

Hence, 301² x 300 - 300³ = 1,80,300
