If the function Q is defined by the formula Q = 5e/(4x(z^2)), by what factor will Q be multiplied if e is quadrupled, x is doubled, and z is tripled?	Choose one.
A) 1/9  B) 2/9  C) 4/9  D) 3/9  E) 2/27
We just need to find the factor thats all,   e -&gt; quadrupled -&gt; 4e   x-&gt; doubled -&gt; 2x   z-&gt; tripled -&gt; 3Z   Hence, Z^2 = 9Z^2   e is in numerator, and x*z in denominator.   Hence,   Additional factor being introduced = 4/2*9   =4/18 = 2/9 = 2/9
