What is associative property of multiplication?
The associative property of multiplication states that the way in which numbers are grouped in a multiplication expression does not change the product.
Besides the associative property, other fundamental properties include the commutative property, distributive property, identity property, and inverse property. These properties help define the behavior of numbers and operations within mathematical systems.
For example
a*(b*c) = (a*b)*c
The grouping of the numbers does no affect the out.
Therefore,
5*n*(n*4) = 5*(n*n)*4
The correct option is 5*(n*n)*4
