To add numbers in scientific notation, we first need to make sure the exponents (the powers of 10) are the same for both numbers.

In this case, we need to compare 10^6 and 10^9. To do this, we need to shift the decimal point in 5×10^6 to the right by 3 places to make the exponents the same. This gives us 5×10^6 = 5,000,000 = 5×10^6.

So now, the two numbers we are adding are:
5×10^6 + 4.213×10^9

Now that the exponents are the same, we can simply add the coefficients:
5 + 4.213 = 9.213

Finally, we express the result in scientific notation:
9.213×10^9 = 9.213×10^9

Apologies for the mistake in my previous response. Let's correct it:

(5×10^6) + (4.213×10^9) = (5×10^6) + (0.4213×10^10)

When adding, we need to have the same exponent for both numbers. To make their exponents the same, we can express 5×10^6 in terms of 10^10:

5×10^6 = 0.5×10^10

Now, we can rewrite our expression with the same exponent:

(0.5×10^10) + (4.213×10^9)

Now, we can simply add the coefficients:

0.5 + 4.213 = 4.713

Therefore, the result in scientific notation is:
4.713×10^10

Let's re-calculate again:

(5×10^6) + (4.213×10^9) = 5×10^6 + 0.4213×10^10
= 5×10^6 + 4.213×10^9
First, let's express 5×10^6 in the same form as 4.213×10^9:
5×10^6 = 0.000005×10^10

Now, let's add the coefficients:
0.000005 + 4.213 = 4.213005

Therefore, the result in scientific notation is 4.213005×10^9.
