संकल्पना:

गणनीयता: यह समूह में तत्वों की संख्या है। 

गणना:

यहाँ, A = [2, 3] 

A × A = [2, 3] × [2, 3]  = [(2, 2), (2, 3), (3, 2), (3, 3)]

A × A × A= [2, 3] × [2, 3] × [2, 3] =  [(2, 2), (2, 3), (3, 2), (3, 3)] × [2, 3]

= [(2, 2, 2), (2, 2, 3), (2, 3, 2), (2, 3, 3), (3, 2, 2), (3, 2, 3), (3, 3, 2), (3, 3, 3)]

इसलिए, n(A× A× A) = 8

इसलिए, गणनीयता = 8 

अतः विकल्प (3) सही है।
