Question

The ratio of 1dm to 1nm

Answer 1

Hello Friend

Here is your answer below,,

we know that

1 decimeter = 1× 10^(-1) meter

1 nanometer = 1×10^(-9) meter

$\frac{1dm}{1nm} \\ = > \frac{1 \times 10 {}^{ - 1} }{1 \times 10 {}^{ - 9} } \\ = > \frac{10 {}^{ - 1} }{10 {}^{ - 9} } \\ = > 10 {}^{ - 1 + 9} \\ = > 10 {}^{8}$

I hope that helps you
