If a*b=`a^2+b^2`,then the value of 2*4 is

If a*b=a^2+b^2, then the value of (4*5)*3 is

If the binary operation * on Z is defined by a*b=a^2-b^2+a b+4 , then value of (2*3)*4 is

If the binary operation * on Z is defined by a * b=a^2-b^2+a b+4 , then value of (2 * 3) * 4 is (a) 233 (b) 33 (c) 55 (d) -55

If angleA=60^(@), b=2 and c=4, then the value of a is

If a=2 and b=-2, find the value of : (i) a^(2)+b^(2) (ii) a^(2)+ab+b^(2) (iii) a^(2)-b^(2)

If a+b+c=0a n da^2+b^2+c^2=1, then the value of a^4+b^4+c^4 is 1 b. 4 c. 1/2 d. 1/4

If (x-a+2b)^(2)+(x-2a+b)^(2)=(a+b)^(2) , then one value of x is
