6.15×10^6 + 4.81×10^7 in scientific notation
The sum of 6.15×10^6 and 4.81×10^7 in scientific notation is:
6.15×10^6 + 4.81×10^7 = 4.81×10^7 + 6.15×10^6 = 5.42×10^7
Evaluate. Express your answer in scientific notation.
6.15 x 10^6 plus 4.81 x 10^7
To add the numbers in scientific notation, we need to make sure the powers of 10 are the same. In this case, we can rewrite 6.15 x 10^6 as 0.615 x 10^7:
0.615 x 10^7 + 4.81 x 10^7 = (0.615 + 4.81) x 10^7 = 5.427 x 10^7
Therefore, 6.15 x 10^6 plus 4.81 x 10^7 is equal to 5.427 x 10^7.
its 5.425x10^7
Apologies for the error in my previous response. You are correct.
6.15 x 10^6 + 4.81 x 10^7 = (6.15 + 48.1) x 10^6 = 54.25 x 10^6 = 5.425 x 10^7
So the correct answer is 5.425 x 10^7.
8.9×10^7+2.7×10^7
To add the numbers in scientific notation, we add the numerical coefficients and keep the same power of 10:
8.9 x 10^7 + 2.7 x 10^7 = (8.9 + 2.7) x 10^7 = 11.6 x 10^7
To express the sum in scientific notation, we write the numerical coefficient as a number between 1 and 10 and the power of 10:
11.6 x 10^7 = 1.16 x 10^8
So, 8.9×10^7 + 2.7×10^7 equals 1.16 × 10^8 in scientific notation.
4.87×10^5
+3.54×10^6
To add the numbers in scientific notation, we need to make sure the powers of 10 are the same. In this case, we can rewrite 4.87 x 10^5 as 0.487 x 10^6:
0.487 x 10^6 + 3.54 x 10^6 = (0.487 + 3.54) x 10^6 = 4.027 x 10^6
So, 4.87 x 10^5 + 3.54 x 10^6 equals 4.027 x 10^6 in scientific notation.
To add numbers in scientific notation, you need to make sure that the exponents are the same. In this case, the exponents are already the same (both are 6), so you can simply add the coefficients.
6.15 × 10^6 + 4.81 × 10^7
First, add the coefficients: 6.15 + 4.81 = 10.96
The sum is 10.96 × 10^6.
However, scientific notation requires that the coefficient is between 1 and 10. In this case, 10.96 is greater than 10. So, we need to adjust the coefficient and the exponent.
To do this, divide 10.96 by 10 and increase the exponent by 1:
10.96 / 10 = 1.096
Increase the exponent by 1: 6 + 1 = 7
The final answer is 1.096 × 10^7.
