Question

(5.1x10^4)+(6x10^5)
Write your answer in scientific notation. Show your work.

Answer 1

To add these two numbers in scientific notation, we first need to make sure that the exponents are the same.

For the first number, 5.1x10^4, we can rewrite it as (5.1x10^4)x(10^1).

Next, we can add the two numbers: (5.1x10^4)x(10^1) + (6x10^5).

Using the properties of exponents, we can simplify the expression by adding the coefficients and keeping the same base: 5.1x10^4 x 10^1 + 6x10^5 = 5.1x10^5 + 6x10^5.

Now, since the bases and exponents are the same, we can add the coefficients: 5.1 + 6 = 11.1.

Finally, we can rewrite the sum in scientific notation as 11.1x10^5.

So, the answer is 11.1x10^5.
