Question

State whether the given statement is true or false

The given expression is numerical expression $215x^{2}yz$

• A. True
• B. False

Answer 1

The correct option is B False

We know that a numerical expression is a mathematical phrase involving only numbers and one or more operational symbols $(+,-,\times ,÷)$.

Here, the given expression is $215x^{2}yz$ in which $x,y$ and $z$ are variables where the exponent of $x$ is $2$ and the exponent of $y$ and $z$ is $1$ and the coefficient is $215$.

Since $215x^{2}yz$ contains variables and also there is no operational symbol.

Hence, $215x^{2}yz$ is not a numerical expression.
