simplify and write scientific notion for the answer. Use the correct number of significant numbers.
(2.74*10^5)(2.2*10^-13)
The answer that i got was 6.03 * 10^-19
anyone did i get this right
The 6.02 looks good, but you should have added exponents
6.02 * 10^(5 + -13) = 6.02 * 10^-8
To simplify and write the scientific notation for the given expression, we need to multiply the two numbers together.
Let's start by multiplying the coefficients:
2.74 * 2.2 = 6.028
Next, we add the exponents:
10^5 * 10^-13 = 10^(5 - 13) = 10^-8
Combining the coefficient and exponent, we have:
6.028 * 10^-8
However, we need to ensure that the final answer has the correct number of significant figures.
Looking at the original numbers, 2.74 has 3 significant figures, and 2.2 has 2 significant figures. Multiplying them together gives us a result with 2 significant figures: 6.0
Therefore, the final answer, with the correct number of significant figures, is:
6.0 * 10^-8
