Answer 2

Answer:

The value of  $\sqrt[3]{216} *\sqrt[3]{-27}$ $=-18$

Step-by-step explanation:

Given : $\sqrt[3]{216} *\sqrt[3]{-27}$

To find : Value of the given expression.

Solution :

• The given expression is $\sqrt[3]{216} *\sqrt[3]{-27}$.
• To find the value of the given expression, we have to first find the value of $\sqrt[3]{216}$ and $\sqrt[3]{-27}$.
• Cube root of a number is defined as the factor which we multiply by itself to get that number.
• Cube root of any negative number is negative and positive number is positive.

• Now, $\sqrt[3]{216} = 6$   and  $\sqrt[3]{-27} = -3$
• ∴   $\sqrt[3]{216} *\sqrt[3]{-27}$ = $6*(-3)$

                       $=-18$

• ∴ The value of  $\sqrt[3]{216} *\sqrt[3]{-27}$ $=-18$
