    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 ...
