Question

1 um x 1 nm divide by 1 cm

​

Answer 1

Answer:

$\frac{1\mu m \times 1nm}{1cm}=$ 10⁻¹³ m

               = 10⁻⁴ nm

               = 10⁻⁷ μm

               = 10⁻¹¹ cm

Explanation:

We know that,

1μm = 10⁻⁶ m

1nm = 10⁻⁹ m

1cm = 10⁻² m

Hence,

$\frac{1\mu m \times 1nm}{1cm}= \frac{10^{-6} \times 10^{9} }{10^{-2} }$

               = 10⁻⁶⁻⁹⁺²

               = 10⁻¹³ m

               = 10⁻⁴ nm

               = 10⁻⁷ μm

               = 10⁻¹¹ cm
