The value of `2a^3-[3a^3+4b^3-{2a^3+(-7a^3)}5a^3-7b^3]` is (a) `-11 a^3+3b^3` (b) `7b^3+3a^3` (c) `11 a^3-3b^3` (d) `(11 a^3+3b^3)`

(5a-7b)^3+(7b-9c)^3+(9c-5a)^3

Add a^3+b^3-3 to the sum of 2a^3-3b^3-3a b+7 and a^3+3a b-9.

The degree of the polynomial 3a ^(2) + 4b ^(3) - 5 ab ^(3) + 7 - 5a ^(7) b ^(5) is

Evaluate : (7)/(2a+3b)-(5)/(2a-3b)

If a=7,darr backslash b=5, then the value of a^(3)-b^(3)+3a^(2)b is (a) 218 (b) 307(c)735 (d) 953

Find the value of a^(3)+b^(3)+c^(3)-3abc if 1) a+b+c=8,ab+bc+ca=19 2) a+b+c=5,a^(2)+b^(2)+c^(2)=11

If (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5, then (3a + 5b) : (9a - 2b)=? यदि (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5 है, तो (3a + 5b) : (9a - 2b)=?

Find the following products: 2a^(3)(3a+5b) (ii) -11a(3a+2b)-5a(7a-2b)( iv) -11y^(2)(3y+7)
