Question

Plse give the answer of this question if any one knows it​

Answer 1

Answer:

Step-by-step explanation:

On cubing both sides, we get

(p + q)^3 = (12)^3

p^3 + q^3 + 3pq( p +q) = 1728

p^3 + q^3 + 3 * 27(12) = 1728

p^3 + q^3 + 972 = 1728

p^3 + q^3 = 1728 - 972

p^3 + q^3 = 756.

Hope it helps you

Answer 2

Hello Friend

The answer of u r question is

Ans:✍️✍️✍️✍️✍️✍️

${p + q}^{3} = {12}^{3}$

${p}^{3} + {q}^{3} + 3 \times 27 \times 12 = 1728$

${p}^{3} + {q}^{3} = 1728 - 972$

=756
