Question

what's the property of
8+3/5=3/5+8
1=1/3*3
4*0=0
N(ca)= (nc)a

Answer 1

commutative property of addition
a+b=b+a

zero property of multiplication
anything multiplied by zero is equal to zero

associative property of multiplication
a(bc)= (ab)c

Answer 2

Each equation represents one property.
The zero property of multiplication is a * 0 = 0
The commutative property of addition is a + b = b + a
The multiplicative inverse property is a * 1/a = a, for a =/= 0
The associative property of multiplication is (ab)c = a(bc)
