Question

a. Calcule:
al 68-6,2+3
e) 60 - [6+ + (33_+
e C5- ()]
ar3.5)2
2 5+32.4​

Answer 1

Resposta:

x = (5²)³ . (5³/5²)⁴

x = 5³•² . (5^3 - 2)⁴

x = 5^6 . (5¹)⁴

x = 5^6 . 5¹•⁴

x = 5^6 . 5⁴

x = 5^6 + 4

x = 5^10

y = (5^9)²/(5⁴ . 5²)²

y = 5^9•2/(5⁴+²)²

y = 5^18/(5^6)²

y = 5^18/5^6•2

y = 5^18/5¹²

y = 5^18 - 12

y = 5^6

x/y = 5^10/5^6 = 5^10 - 6 = 5⁴
