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) Superscr
Rina8888 [55]

Answer:

Option 1 - y cubed z superscript 4

Step-by-step explanation:

Given : Expression y times y times y times z times z times z times z.

To find : Which expression is equivalent to given expression ?

Solution :

Re-write the expression as,

y \times y \times y \times z \times z \times z \times z

Write the number of time value repeat itself as the power,

y \times y \times y \times z \times z \times z \times z=y^3\times z^4

y \times y \times y \times z \times z \times z \times z=y^3z^4

or we can say that the expression is y cubed z superscript 4.

Therefore, option 1 is correct.
