Use addition to find the sum the two following scientific notations. Your answer should be written in scientific notation form.
(2*10^8)+(7*10^6)
To add these two numbers in scientific notation form, we need to ensure that the exponents are the same. Let's make both exponents equal to 8.
2 * 10^8 can be written as 20 * 10^7 (increasing the exponent by 1)
7 * 10^6 can be written as 0.7 * 10^7 (decreasing the exponent by 1)
Now, we can add them together:
20 * 10^7 + 0.7 * 10^7 = 20.7 * 10^7
Therefore, the sum of (2*10^8) + (7*10^6) is 20.7 * 10^7.
To add the two scientific notations, we need to ensure that the exponents are the same. In this case, the exponents are already the same (both 8), so we can add the corresponding coefficients.
The sum of (2*10^8) and (7*10^6) is:
(2 + 7) * 10^8 = 9 * 10^8
Therefore, the answer is 9 * 10^8 in scientific notation form.
To find the sum of two scientific notations using addition, follow these steps:
Step 1: Add the coefficients (the numbers in front of the multiplication symbol).
In this case, the coefficients are 2 and 7.
2 + 7 = 9
Step 2: Keep the same base (10) and add the exponents.
In this case, the exponents are 8 and 6.
10^8 + 10^6 = 10^(8+6) = 10^14
Step 3: Combine the coefficient and the base with the exponent to write the answer in scientific notation.
The sum is 9 * 10^14.
Therefore, (2*10^8) + (7*10^6) equals 9*10^14 in scientific notation form.
