Use the properties of exponents to rewrite the expression.

(-3yz) (-3yz) (-3yz) (-3yz)

Answer is 81y^4z^4

Step-by-step explanation:

The expression is (-3yz) (-3yz) (-3yz) (-3yz).

Since all the four terms have power 1:

(-3yz) ^1 (-3yz) ^1 (-3yz) ^1 (-3yz) ^1

We know that we can add the powers if the terms have same base

So,

= (-3yz) ^1+1+1+1

= (-3yz) ^4

= (-3) ^4 (y) ^4 (z) ^4.

If the power is an even number than the negative sign changes into positive sign.

=3^4y^4z^4

=81y^4z^4

Thus the answer is 81y^4z^4 ...
