Mason says that 350 + 2 x 104 can be written in scientific notation as 55 x 104 Is Mason correct?
Explain your answer using mathematics,

Answer 1

Answer:

Mason's affirmation is:

• Incorrect.

Step-by-step explanation:

The first form you can see that Mason is wrong is operating:

• 350 + 2 x 104 = 558 (remember that first, you must do the multiply and next the add by hierarchy of operations).
• 55 x 104 = 5720

How the two operations didn't have the same result, the second form isn't a scientific notation of the first form.

The second case is because a scientific notation regularly is written in the next form:

• 350 + 2 x 104 = 558 = 5.58 x 10^2

I used the result (558) then ubicate the point in the units (5) and the rest  are decimals, next I used 10 and the number of digits that I moved the point (2).
