If v, w, x, y, and z are positive integers, which of the following could not become a terminating decimal? Pick one:
A) 33/2^(4x) B) 34/5^(2y) C) 35/100^z D) 36/4^w E) 37/3^(5v)
Knowledge of Decimal equivalent Fractions will work wonders here , no need to consider the Numerator part   1/ 2= 
<gadget id="calculator">1/ 2</gadget>
<output>1/2 = around 0.5</output>
0.50 ( Terminating )   1/5= 
<gadget id="calculator">1/5</gadget>
<output>1/5 = around 0.2</output>
0.20 ( Terminating )   1/100= 
<gadget id="calculator">1/100</gadget>
<output>1/100 = around 0.01</output>
0.01 ( Terminating )   1/4= 
<gadget id="calculator">1/4</gadget>
<output>1/4 = around 0.25</output>
0.25 ( Terminating )   1/3= 0.33 ( Non Terminating )   Check the above rule with any higher powers the result will be same.....   Among the given options only (37/3^(5v)) has a non terminating denominator , so this will be our answer..
<result>E</result>
