Which shows the expression below simplified?
(3.6 × 1015) + (1.8 × 1012)
a. 3.60018 × 10^15
b. 3.902 × 10^14
c. 3.618 × 10^15
d. 3.6018 × 10^15
To simplify the given expression, we need to perform addition of the two numbers in scientific notation.
The expression is:
(3.6 × 10^15) + (1.8 × 10^12)
To add these numbers, we need to make sure that the exponents are the same. Since we have 15 and 12 as exponents, we can rewrite the expression as:
(3.6 × 10^15) + (0.018 × 10^15)
Now that the exponents are the same, we can add the coefficients:
3.6 + 0.018 = 3.618
Finally, we multiply the sum by the common exponent of 10^15:
3.618 × 10^15
So, the simplified expression is 3.618 × 10^15.
Therefore, the correct answer is c. 3.618 × 10^15.
