Answer:

52.4.

Step-by-step explanation:

This is the difference of 2 squares:

a^2 - b^2 = (a - b)(a + b)

(7.62^2 - (2.38)^2

= (7.62 - 2.38)(7.62 + 2.38)

= 5.24 * 10

Answer:

52.4

Step-by-step explanation:

a²-b² = (a-b)(a+b)

Similarly,

(7.62)²-(2.38)²

= (7.62-2.38)(7.62+2.38)

= (5.24)(10)

= 52.4
