Step-by-step explanation:
Answer: a and d
Step-by-step explanation:
First of all, we need to make a analysis of each letters:
a. factoring 32 = 2.2.2.2.2 = 

then,
16 = 
but 
in conclusion that, this inequality is correct
b. 27 = 
this first situation is equal to 
the second situation is:
81 = 
and 
it's a mistake.
c. factoring 9: 
< 
it's wrong.
d. factoring 8 = 
factoring 32 = 
> 
This is true.
Finally.. our correct answers is a and d.
The easiest way to do this is to plug in the numbers for the variebles and see if they equal the same in both sides. lets try the first one 5(1)+2(-3)=-1, multiply the nmbers to get 5-6=-1 now simplify to get the answer of -1=-1, they both equal the same so this means that the first option is the correct one
Hope this helps
