Question

the expression incolves two numbers written in scientific notation. which is the simplified form of this expression?

Answer 1

3 x 10^11

Explanation:

We are given the following expression, in scientific notation:

`(9.33\ast10^7)/(3.11\ast10^(-4))`

To solve the division, we can divide the values(9.33 and 3.11), and subtract the exponents, while keeping the base. So

`(9.33\ast10^7)/(3.11\ast10^(-4))=(9.33)/(3.11)\ast10^(7-(-4))=3\ast10^(7+4)=3\ast10^(11)`

The answer is 3 x 10^11
