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

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

If a=7,\ b=5,\ c=3, then the value of a^2+b^2+c^2-a b-b c-c a\ i s -12 (b) 0 (c) 8 (d) 12

If a=7, b=5, c=3, then the value of a^2+b^2+c^2-a b-b c-c a i s -12 (b) 0 (c) 8 (d) 12

If a binary operation * is defined on the set Z of integers as a*b=3a-b, then the value of (2*3)*4 is (a) 2 (b) 3 (c) 4 (d) 5

If 5a=6b+7 and a -b =3, what is the value of b/2 ?

If [(2a+b,a-2b),(5c-d,4c+3d)]=[(4,-3),(11,24)] then the value of a+b-c+2d is (a) 8 (b) 10 (c) 4 (d) -8

"If A"= ({:(2, 3),(5, 1):}), B = ({:(a, b),(c, d):}) and AB = -13I, then find the value of a + b - c + d. (a) 5 (b) 3 (c) 2 (d) 1

If a^(3) + b^(3) = 218 and a + b = 2 , then the value of ab is :
