Log (base 8) 2 +log (base 8) 4x^2 =1

Log (base8) 2 = 1/3

Log (base 8) (4x^2) + Log (base 8) 4 + 2Log (base 8) x = 2/3 + 2 Log (base 8) x

1/3 + 2/3 + 2 Log (base 8) x = 1

2 Log (base 8) x = 0

Log (base 8) x = 0

x = 8^0

x = 1.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
