Question

any of the 2 questions would help please! thank you so much

Answer 1

3 is true.
Break into like parts.
18/9 is two
X to the 4 plus x squared is x to the 6
Y plus y to the 4 is y to the 5
Z to the negative 2 is shown as z
This means everything is correct.

I am not sure but I think 4 is true.
All numbers are positive.
Odd numbers and even numbers do not cross (empty set then).
This is based off the fact of odd and even numbers are just odd and even.

Answer 2

Answer:

3) False, should be divided by z²

4) True

Step-by-step explanation:

3) 18($\frac{1}{9}$x⁴y)(x²y⁴z⁻²)   ⇒   2x⁶y⁵/z²
