Add 7.3×107+1.8×107 . Which is the correct sum?(1 point) Responses 9.1×1014 9.1 times 10 superscript 14 baseline 9.1+107 9.1 plus 10 superscript 7 baseline 9.1×107 9.1 times 10 superscript 7 baseline 8.1×107
The correct sum is 9.1×107.
To add 7.3×10^7 and 1.8×10^7, you need to add the coefficients while keeping the same exponent.
7.3 + 1.8 = 9.1
Therefore, the correct sum is 9.1×10^7.
To find the sum of 7.3×10^7 and 1.8×10^7, you need to add the numbers in front of the exponential notation and keep the same base (in this case, 10) for the exponential part.
The calculation is as follows:
7.3×10^7 + 1.8×10^7 = (7.3 + 1.8) × 10^7
Adding the numbers in front of the exponential notation:
7.3 + 1.8 = 9.1
So the correct sum is 9.1×10^7.
