" 66.If the curves "(x^(2))/(alpha)+(y^(2))/(4)=1" and "y^(3)=16x" intersect at right angles,then the value of "alpha" is "

If the curves (x^(2))/(alpha)+(y^(2))/(4)=1 and y^(2)=16x intersect at right angles,then a value of alpha is

If the curves (x^(2))/(alpha)+(y^(2))/(4)=1 and y^(3)=16x intresect at right angles, then a value of alpha is

If the curves (x ^(2))/(a ^(2))+ (y^(2))/(4)= 1 and y ^(3)= 16x intersect at right angles, then:

If the curves (x ^(2))/(a ^(2))+ (y^(2))/(4)= 1 and y ^(2)= 16x intersect at right angles, then:

If the curves (x ^(2))/(a ^(2))+ (y^(2))/(4)= 1 and y ^(2)= 16x intersect at right angles, then:

If the curves (x^(2))/(a^(2)) + (y^(2))/(12) = 1 and y^(3) = 8x intersect at right angles, then the value of a^(2) is equal to

If the curves (x ^(2))/(a ^(2)) + (y ^(2))/(12) =1 and y ^(3) =8x intersect at right angles, then the value of a ^(2) is equal to

If the curves x^(2)/a^(2)+ y^(2)/4 = 1 and y^(3) = 16x intersect at right angles, then a^(2) is equal to

If the curves (x^(2))/(a^(2))+(y^(2))/(4)=1 and y^(3)=16x intersect at right angles, show that a^(2)=(4)/(3) .
