Angora wool obtainted from rabbits has fibers with a diameter of about 1*10^-6 cashmere obtainted from goats has fibers with a diameter of about 1.45*10^-5 meter.
find the sum of the diameter of the two fabrics?
Assuming that both diameters are in meters, we have
1 * 10-6 + 1.45 * 10-5 =
1 * 10-6 + 14.5 * 10-6 =
10-6 [ 1 + 14.5] =
10-6 [ 15.5] =
10-5 * 1.55 =
1.55 * 10-5 meters
