5,200,000×(8.3×10^2)−(3.1×10^8) answer in scientific notation

4.006 x 10^9

Step-by-step explanation:

5,200,000×(8.3×10^2)−(3.1×10^8)

5,200,000×830-(3.1×10^8)

5,200,000×830-310000000

4316000000-310000000

4006000000

4006000000=4.006 x 10^9=

So, we need to move the decimal point 9 places to the right.

This means that the power of 10 will be positive 9.

4.006000000 ( which can be written as 4.006 ) and

Exponent part = 9

So, the solution is:

4.006 x 10^9
