The common factor of `a_2 m^4 and a_4 m^2` is (a) `a_4m^2` (b) `a_2m^2` (c) `a_m^4` (d) `a_4m^2​`

Find the value of ( m^4 - m^2n^2) ÷ m^2 is

Factories: m^(4) + 2m^(2) n ^(2) +n ^(4)

The slope of common tangents to x^(2)+4y^(2)=4 and x^(2)+y^(2)=3 is m ,then m^(2) is

The line y=mx+1 is a tangent to the parabola y^2 = 4x if (A) m=1 (B) m=2 (C) m=4 (D) m=3

If the diagonal of a square is sqrt(8) metre,then its area is: 8m^(2)( b) 4m^(2)( c) 16m^(2)( d) 6m^(2)

If tantheta+sintheta=m and tantheta-sintheta=n , then the value of m^2-n^2 is equal to (a)4 mn (b) 2sqrt(mn) (c) 4sqrt(mn) (d) 2sqrt(m//n)

A man walking at the speed of 4kmph crosses a square field diagonally in 3 minutes.The area of the field is (a) 18000m2 (b) 19000m2 (c) 20000m2 (d) 25000m2
