Answer:
The correct options are 1, 2 and 3.
Step-by-step explanation:
The given expression is
[tex](hc)y[/tex]
We need to find the expressions which are equivalent to the given expression.
Using multiplication the given expression can written as
[tex]hcy[/tex]
So, option 1 is correct.
Using the Associative property of multiplication the given expression can be rewritten as
[tex]h(cy)[/tex] [tex][\because (ab)c=a(bc)][/tex]
Using the commutative property we get
[tex]h(yc)[/tex] [tex][\because ab=ba][/tex]
[tex]hyc[/tex]
Options 2 and 3 are correct.
Therefore, the correct options are 1, 2 and 3.
