Answer:
62
Step-by-step explanation:
WHEN YOU START FACTORISING YOU WILL FIND THE FOLLOWING
3968=2X2X2X2X2X2X2X31
NOW, WE CAN SEE THAT THERE ARE 3 PAIRS OF 2 AND THERE IS ONE 2 AND ONE 31 WHICH DO NOT FORM A PAIR. SO, THE SMALLEST NUMBER WOULD BE
2X31=62 WHICH CAN BE MULTIPLIED TO 3968 TO MAKE IT A PERFECT SQUARE. DO LET ME KNOW, IF IT WAS HELPFUL.
