The value of `(a^4-a^2b^2)-:a^2` is:

Find the value of ( a^4 - a^2*b^2 ) ÷ a^2 is ( a ) x^2( a - b )^2 ( b ) ( a + b )( a - b ) ( c ) b ( a - b ) ( d ) a ( a - b )

Find the value of ( a^2/b^2 + b^2/a^2 ) is ( a ) ( a/b + b/a )^2 - 2 ( b ) ( a/b + b/a )^2 + 2 ( c ) ( a/b + b/a )^2 + 4 ( d ) ( a/b + b/a )^2 - 4

If a=3^((1)/(4))+3^(-(1)/(4)) and b=3^((1)/(4))-3^(-(1)/(4)) then the value of 3(a^(2)+b^(2))^(2)

If (a)/(2b) = (c )/(d) = (e )/(3f) , then the value of (2a^(4)b^(2)+3a^(2)c^(2)-5e^(4)f)/(32b^(6)+12b^(2)d^(2)-405f^(5)) is

If a^(2) +b^(2) = x, ab = y then the value of (a^(4) +b^(4))/(a^(2) -ab sqrt(2) +b^(2)) is

If a+b+c=0&a^(2)+b^(2)+c^(2)=1 then the value of a^(4)+b^(4)+c^(4) is

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1, then the value of a^(4)+b^(4)+c^(4) is
