Dividing the numbers given above, we obtain an answer of 2.380952381 x 10^-9. Writing the answer into two significant figures, then it will be 2.4x10^-9. Scientific notation is a method scientists use in order to handle very large or small numbers.

Dividing the numerical values of the given gives an answer of 0.238. Now, dividing the x10's gives an answer of x10^-8. The answer is supposedly 0.238x10^-8. Converting this value to a scientific notation with only 2 significant figures gives 2.4x10^-9.

What is the product?<br><br> (5.63 x 10^5) x 5,600,000
victus00 [196]

Answer: 3.1528 \times 10^{12}.


Step-by-step explanation: Given expression (5.63 \times 10^5) \times 5,600,000.

In order to find the product of given expression, we need to convert 5,600,000 into scientific notation, because other number is also in scientific notation.

5,600,000 = 5.6 × 10^6.

Therefore, (5.63 \times 10^5) \times 5,600,000 =(5.63 \times 10^5) \times (5.6 \times 10^6).

Now, multiplying 5.63 × 5.6 first, we get 31.528.

And 10^5 × 10^6 = 10^11.

Therefore,

(5.63 \times 10^5) \times (5.6 \times 10^6) = 31.528 \times 10^11.

<h3>Or 3.1528 × 10^12.</h3>
