Calculate the following and write your answer in scientific notation

6.6 x 10^6
(8.8 x10^2) x (2.5 x 10^3)

To calculate the first expression, 6.6 x 10^6, we simply multiply 6.6 by 10^6.

6.6 x 10^6 = 6.6 * (10^6)

To multiply a number by 10 raised to a certain power, we move the decimal point to the right by that many places. In this case, the exponent is positive, so we move the decimal point 6 places to the right.

6.6 * (10^6) = 6,600,000

Therefore, the answer is 6.6 x 10^6 is equal to 6,600,000.

Now, let's calculate the second expression, (8.8 x 10^2) x (2.5 x 10^3).

To multiply these two numbers, we multiply the coefficients (8.8 x 2.5) and add the exponents (10^2 x 10^3).

8.8 x 2.5 = 22

10^2 x 10^3 = 10^(2+3) = 10^5

Putting it all together, we have:

(8.8 x 10^2) x (2.5 x 10^3) = 22 x 10^5

Similar to the previous example, when we multiply a number by 10 raised to a certain power, we move the decimal point to the right by that many places. In this case, the exponent is positive, so we move the decimal point 5 places to the right.

22 x 10^5 = 22,000,000

Therefore, the answer to (8.8 x 10^2) x (2.5 x 10^3) in scientific notation is 2.2 x 10^7.
