Question

the value of (8.6)²-(7.6)² is 16.2​

Answer 1

Answer:

(8.6)² - (7.6)² = 16.2

Step-by-step explanation:

We have,

(8.6)² - (7.6)²

Now, we know that,

x² - y² = (x + y)(x - y)

Then,

(8.6)² - (7.6)²

= (8.6 + 7.6)(8.6 - 7.6)

= (16.2)(1)

= 16.2 × 1

= 16.2

Hence,

(8.6)² - (7.6)² = 16.2
