4z3(3z-1)+7(3z-1)
what is the goal? to simplify? if so it would be:
12z^4-4z^3+21z-7
z^2 means z squared, z^3 z cubed, etc.
i assumed that the 4z3 at the beginning was four z cubed...
4z^3*(3z-1)+7(3z-1)=
4z^3*(3z-1)+(7*3)*z+7*(-1)=
4z^3*3z+4z^3*(-1)+21z-7=
12z^4-4z^3+21z-7

To simplify the expression 4z^3(3z - 1) + 7(3z - 1), we can distribute the terms inside the parentheses.
First, distribute 4z^3 to both terms inside the parentheses:
4z^3 * 3z = 12z^4
4z^3 * -1 = -4z^3
Now we have:
12z^4 - 4z^3 + 7(3z - 1)
Next, distribute 7 to both terms inside the parentheses:
7 * 3z = 21z
7 * -1 = -7
Now we have:
12z^4 - 4z^3 + 21z - 7
So, the simplified expression is:
12z^4 - 4z^3 + 21z - 7.
