10 days is twice the half-life. After 5 days, can expect \dfrac{25}2 grams to remain; after another 5 days, you'd be left with \dfrac{25}4 grams.

Lady bird [3.3K]

Answer:

-39

Step-by-step explanation:

\left(-3\right)^3-\sqrt[3]{27}-4^3\left(\sqrt[3]{64}-\left(2\right)\left(2\right)\right)-\frac{\left(3\right)^3\left(2\right)}{6}

-27-3-64\left(4-4\right)-\frac{54}{6}

-27-3-\frac{54}{6}

-27-3-9

Which gives us -39.
