State the property used in the following equation: (29 × 36) × 18 = 29 × (36 × 18)

We know,

Let A, B and C are three whole numbers, then as per associativity of multiplication,$\mathrm{A}\times (\mathrm{B}\times \mathrm{C})=\mathrm{C}\times (\mathrm{A}\times \mathrm{B})$.

Here, given that, (29 × 36) × 18 = 29 × (36 × 18)

Hence, The property used in the statement is the associative property of multiplication.
