Answer:

0.0000000135 in scientific form is $1.35 * 10^{-8}$

Explanation:

According to question,

0.0000000135 is to be converted to scientific form to two significant figures

0.0000000135 can also be written as$\frac{135}{10000000000}$

135 in decimal form can be written as  $(1.35 * 100) \text { or }\left(1.35 * 10^{2}\right)$

And 10000000000 =$10^1^0$

Therefore,

$\frac{135}{10000000000}=\frac{1.35 * 10^{2}}{10^{10}}$

$\frac{1.35 * 10^{2}}{10^{10}}=1.35 * 10^{2-10}=1.35 * 10^{-8}$

Thus, 0.0000000135 in scientific form is $1.35 * 10^{-8}$
