Simplify the expression. Assume all variables represent positive real numbers.<br><br>∛864

Mekhanik [1.2K]

$\bf \sqrt[3]{864}\qquad 
\begin{cases}
864\to 2\cdot 2\cdot 2\cdot 2\cdot 2\cdot 3\cdot 3\cdot 3\\
\qquad 2^3\cdot 2^2\cdot 3^3
\end{cases}
\\\\\\
\sqrt[3]{\boxed{2^3}\cdot 2^2\cdot \boxed{3^3}}\implies \boxed{2}\cdot \boxed{3}\sqrt[3]{2^2}\implies 6\sqrt[3]{4}$

An $42 item was marked down by 50%<br><br> what is the new cost of the item?

Nataly_w [17]

Answer:

New Cost of item is $\$ 21$

Step-by-step explanation:

Given:

Original Cost of item = $\$ 42$

Item was marked down by $50\%$

To Calculate Cost after $50\%$ marked down we need to multiply original cost by 50 and then divide by hundred.

Cost after marked down = $\frac{42 \times 50}{100}= \$21$

Now New cost of the item is calculated by Subtracting Cost after $50\%$ marked down by Original Cost of item.

New cost of the item = $\$ 42 - \$ 21 = \$21$
