Question

sendo x= (2 -1/2) -² e y = (1+1/3)-¹ , calcule x° y

Answer 1

Resposta:

Explicação passo-a-passo:

x= (2 -1/2) -² e y = (1+1/3)-¹

calcule x° y

x = (2 - 1/2) ^ (-2)

x = [(2.2 - 1)/2] ^ - 2

x = (3/2) ^ - 2

x = 2/3 ^2

x = 4/9

y = (1+1/3) ^ (-1)

y = [(3.1 + 1)/3] ^ - 1

y = 4/3 ^ (-1)

y = 3/4

= x°.y

= (4/9)^0 . 3/4

= 1 . 3/4

= 3/4
