Question

evaluate 48×52 without actual multiplication​

Answer 1

48 × 52 = 2496

Step-by-step explanation:

To find the value of 48 × 52 without using actual multiplication, we use algebraic identity to find the multiplication value.

Now, 48 × 52

= (50 - 2) × (50 + 2)

[ Here we get a form (a - b) (a + b), which results to a² - b², an algebraic identity. ]

= 50² - 2²

= 2500 - 4

= 2496
