Question

1um x 1nm / 1Cm = A) 10^-13 B) 10^-15 C) 10^-17 D) 10^-11

Answer 1

1 μm * 1 nm / 1 cm = 10^-11

Explanation:

To find the value of 1 μm * 1 nm / 1 cm, let's convert all the values to one unit.

1 μm = 1 * 10^-4 cm

1 nm = 1 * 10^-7 cm

So 1 μm * 1 nm / 1 cm = 10^-4 * 10*-7 / 1 cm/cm

= 10^(-4+-7)

Adding the powers by applying the exponent product rule.

= 10^-11

Option D is the answer.
