Answer 1

Answer: The result of the given calculation is
`2.98* 10^(-4)cm`

Step-by-step explanation:

Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form.

We are given an expression:

`\Rightarrow (0.0263cm^2)/(88.2cm)`

The operation carried out in the above expression is division operation. The units are also treated in the same way.

The solution for the above expression is:

`\Rightarrow (0.0263cm^2)/(88.2cm)=0.000298cm`

The value in scientific notation is
`2.98* 10^(-4)cm`

Hence, the result of the given calculation is
`2.98* 10^(-4)cm`
