Question

question
evaluate. express your answer in scientific notation.
$3.5 \times 10^{-5} + 1.3 \times 10^{-5}$
answer attempt 1 out of 2
answer: $\square \times 10^{\square}$

Explanation:

Step1: Factor out \(10^{-5}\)

Since both terms have the same power of 10 (\(10^{-5}\)), we can factor it out. So we get \((3.5 + 1.3)\times10^{-5}\).

Step2: Add the coefficients

Now we add the coefficients \(3.5\) and \(1.3\). \(3.5+1.3 = 4.8\).

Step3: Combine the results

Putting it back together with the factored out \(10^{-5}\), we have \(4.8\times10^{-5}\).

Answer:

\(4.8\times10^{-5}\)
