Nice class... eagerly waiting for your next class
a³ + b³ = 4059(a² - ab + b²) = 405a² - ab + b² = 45 a + b = 9, and a² + 2ab + b² = (a + b)² = 9² = 81. a² + 2ab + b² = 81a² + 2ab + b² - 2ab = 81 - 2aba² + b² = 81 - 2ab a² - ab + b² = 45:81 - 2ab - ab = 4581 - 3ab = 45-3ab = -36ab = 12Therefore, the value of ab is 12.
We can use the formula (a+b)^3 = a^3 + b^3 + 3ab(a+b) i.e, 729 = 405 + 27ab 27ab = 324Hence, ab = 12This saves a lot of time.

729=405+27ab
27ab=324
Ab=12
Nice class... eagerly waiting for your next class
a³ + b³ = 405
9(a² - ab + b²) = 405
a² - ab + b² = 45
a + b = 9, and a² + 2ab + b² = (a + b)² = 9² = 81.
a² + 2ab + b² = 81
a² + 2ab + b² - 2ab = 81 - 2ab
a² + b² = 81 - 2ab
a² - ab + b² = 45:
81 - 2ab - ab = 45
81 - 3ab = 45
-3ab = -36
ab = 12
Therefore, the value of ab is 12.
We can use the formula
(a+b)^3 = a^3 + b^3 + 3ab(a+b)
i.e, 729 = 405 + 27ab
27ab = 324
Hence, ab = 12
This saves a lot of time.
