Question

Evaluate {(-2/3)²} -2​

Answer 1

Answer:

(1.05)(9.5)

=(1.05)× 10 (9.5) / 10

= (10.5) (9.5) /10

10.5 written as (10 + 0.5)

9.5 written as (10 - 0.5)

(10.5) (9.5) /10 = (10 + 0.5) (10 - 0.5) /10

Using Algerbic identity (a + b) (a - b) = a² - b²

(10 + 0.5) (10 - 0.5) /10 = (10)² - (0.5)² /10

= (100 - 0.25) /10

= (99.75) /10

= 997.5
