If `(2z_(1))/(3z_(2))` is purely imaginary number, then `|(z_(1)-z_(2))/(z_(1)+z_(2))|^(4)` is equal to

If (2z_(1))/(3z_(2)) is purely , an imaginary number , then |(z_(1) - z_(2))/(z_(1) + z_(2))| is equal to

if (5z_(2))/(7z_(1)) is purely imaginary number then |(2z_(1)+3z_(2))/(2z_(1)-3z_(2))| is equal to

If (3 z_(1))/(5 z_(2)) is purely imaginary, then |(2z_(1)-z_(2))/(2z_(1) + z_(2))| is equal to _________

If (2z_1)/(3z_2) is purely imaginary then |(z_(1)-z_(2))/(z_(1)+z_(2))|

If z_(1),z_(2) are complex number such that (2z_(1))/(3z_(2)) is purely imaginary number,then find |(z_(1)+z_(2))/(z_(1)+z_(2))|

If (2 z _(1))/(3z _(2)) is a purely imaginary, then | ( z _(1) - z _(2))/( z _(1) + z _(2))| is:

If (5z_(1))/(7z_(2)) is purely imaginary then |(2z_(1)+3z_(2))/(2z_(1)-3z_(2))|=
