find the value of $sqrt3{343}$.
Answer
Explanation:
Step1: Recall cube - root definition
The cube - root of a number $x$, denoted as $\sqrt[3]{x}$, is a number $y$ such that $y^3=x$.
Step2: Find the number whose cube is 343
We know that $7\times7\times7 = 7^3=343$. So, $\sqrt[3]{343}=7$.
Answer:
$7$
