Q. Which equation shows the associative property of multiplication?Choices:(A) (h⋅j)⋅k=h⋅(j⋅k)(B) h⋅k+j⋅k=(h+j)⋅k(C) h=h⋅1(D) 0⋅h=0
Define Associative Property: Recall the definition of the associative property of multiplication. The associative property states that the way in which factors are grouped in a multiplication problem does not change the product. In mathematical terms, this property is expressed as (a×b)×c=a×(b×c).
Examine Choice (A): Examine choice (A) to see if it demonstrates the associative property of multiplication. The equation given is h \cdot j) \cdot k = h \cdot (j \cdot k)\. This matches the form of the associative property, where the grouping of the factors is changed but the order of the factors remains the same.
Examine Choice (B): Examine choice (B) to see if it demonstrates the associative property of multiplication. The equation given is \(h \cdot k + j \cdot k = (h + j) \cdot k. This does not match the form of the associative property; instead, it shows the distributive property, which involves both addition and multiplication.
Examine Choice (C): Examine choice (C) to see if it demonstrates the associative property of multiplication. The equation given is h=h⋅1. This does not match the form of the associative property; instead, it shows the identity property of multiplication, which states that any number multiplied by one equals itself.
Examine Choice (D): Examine choice (D) to see if it demonstrates the associative property of multiplication. The equation given is 0⋅h=0. This does not match the form of the associative property; instead, it shows the zero property of multiplication, which states that any number multiplied by zero equals zero.
Conclude Correct Equation: Conclude that the equation which correctly demonstrates the associative property of multiplication is the one from choice (A), which is (h⋅j)⋅k=h⋅(j⋅k).
