Question

Get the algebraic expressions in the following cases using variables, constants, and arithmetic operations:

The number $z$ multiplied by itself.

Answer 1

Express the given statement as an algebraic expression

1. The number $z$ multiplied by itself implies that the value of number $z$ is multiplied to the value of number $z$ again.
2. In this primary arithmetic operation, multiplication takes place i.e. $z\times z$ which can be expressed as $z^2$.

Hence, the algebraic expression for the number $z$ multiplied by itself is $z^2$.
