### Hint

Try to find a solution that does not involve the use of addition or subtraction.### Answer

On the right side of the equation, draw a diagonal line between the 4 and the 3, such that the right side of the equation is 4/32. On the left side of the equation, draw an identical line between the first 1 and the 2, and draw a small 7 to the upper-right of the 2.You should have:

1 / 2^7 x 1 6 = 4 / 3 2 (In this case, the ^ indicates that the 7 is an exponent.)
