1 micrometer is $$10^{-a}$$ hectometer. What is value of a?


ANSWER

8


SOLUTION
$$1$$ micrometer $$=10^{-6}$$ meter and $$1$$ hectometer $$=10^2 $$ meter
So, $$1$$ micrometer $$=10^{-6}\times \dfrac{10^2}{10^2}$$ meter $$=\dfrac{10^{-6}}{10^2}\times 1$$ hectometer $$=10^{-8}$$ hectometer
Thus, $$a=8$$
