Answer 1

Hey

.0081/300 = .000027 = 2.7 x 10^-5

Hoped I Helped

Answer 2

`(0.0081)/(300)`

`2.7 * 10^(-5)`

so this is given as

`3 * 10^(-5)`

Step-by-step explanation:

As we know that when two or more numbers are multiplied or divided then the result is always given by least number of significant numbers.

So here we have to divide two numbers

a = 0.0081

total significant digits = 2

b = 300

total significant digits = 1

as we divide two number then we got

`(a)/(b) = (0.0081)/(300)`

`(a)/(b) = 2.7 * 10^(-5)`

now by rounding off the above number to one significant digit we have

`(a)/(b) = 3 * 10^(-5)`
