Answer 1

`B\text{. 8.0023 }\cdot10^4`

Step-by-step explanation

We want to write the number given in scientific notation. The number is 80,023

Putting a number in scientific notation involves writing that number as a product of a number between 1 and 10 and a power of 10.

We do this by moving the decimal point from behind the last digit of the number (3) to just after the first digit (8).

We move the decimal point 4 times to the left, that is why the power of 10 is +4.

So, we have that 80,023 becomes:

`80,023\text{ = 8.0023 }\cdot10^4`
