Question Simplify expressions like $a^3$, $6yx$, $4x^2$, $15x^2y$, and $-4y^2z^2$.

Studdy Solution
Simplify expression (e) $-4 \times z \times y \times z \times y$ by first multiplying the constant with the negative sign and then combining the like variables using the properties of exponents.
$$-4 \times z \times y \times z \times y = -4y^2z^2$$
The simplified expressions are as follows: a) $a^3$ b) $6xy$ c) $4x^2$ d) $15yx^2$ e) $-4y^2z^2$
