Question

125x^3 + 64y^3÷5x+4y​

Answer 1

Answer:

$125 x + 64y$

$\sqrt{125x } + \sqrt{64y}$

$= 5x + 4y$

Answer 2

Answer:

Solution :-

➜ 125x³ + 64y³ ÷ 5x + 4y

➞ (5x)³ + (4y)³/(5x + 4y)

➞ (5x + 4y) {(5x)² - 5x × 4y + (4y)²}/(5x + 4y)

➞ (5x + 4y) (25x² - 20xy + 16y²)/(5x + 4y)

After cancellation, we get

➞ (25x² - 20xy + 16y²)

∴ The answer of this question is

(25x² - 20xy + 16y²)

Formula used :-

➜ a³ + b³

➞ (a + b) (a² - ab + b²)
