Question

Determine a taxa percentual correspondente a (10%)2-(5%)2. alguém pode me ajudar por favor?

Answer 1

Taxa = (10%)² - (5%)² 
Taxa = (10/100)² - (5/100)² 
Taxa = (2/20)² - (1/20)² 
Taxa = 4/400 - 1/400 
Taxa = 3/400 
Taxa = 0,0075 
Taxa = 0,75%

Answer 2

taxa=(10%)^2-(5%)^2

taxa=(10/100)^2-(5/100)^2

taxa=(100/10000)-(25/10000)

taxa=  100/10000-25/10000

taxa=75/10000

taxa=0,0075

taxa=0,75%
