Work Step by Step

We can use order of operations to perform the indicated operations. Step by step: $\frac{10-24+(-6)}{\sqrt 16(-5)}=\frac{10-24-6}{\sqrt16(-5)}=\frac{10-24-6}{4\times-5}=\frac{10-24-6}{-20}=\frac{-14-6}{-20}=\frac{-20}{-20}=1$ Recall that $\sqrt 16=4$, because $4^{2}=16$.

After you claim an answer you’ll have 24 hours to send in a draft. An editor will review the submission and either publish your submission or provide feedback.
