Question

Which expression is equivalent to y times y times y times z times z times z times z?
y cubed z Superscript 4
12xy
(y z) Superscript 7
7xy

Answer 1

The expression \( y \times y \times y \times z \times z \times z \times z \) can be rewritten using exponents:

- \( y \times y \times y = y^3 \)
- \( z \times z \times z \times z = z^4 \)

Thus, the entire expression can be combined as:

\[
y^3 z^4
\]

Therefore, the expression that is equivalent to \( y \times y \times y \times z \times z \times z \times z \) is:

\[
y^3 z^4
\]

So the correct answer is \( y^3 z^4 \).
