Evaluate. Express your answer in scientific notation.
6.15 x 10^6 plus 4.81 x 10^7
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.
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.
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.
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
+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.
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.
