Question

Se a = -3^2 , b = -2^3 , c = -(-4)^2 e x = (1/9) ^A+B-C , entao x -1/2 ^ ?

Answer 1

Se a = -3² , b = -2³ , c = -(-4)² e x = (1/9) ^A+B-C , então x -¹/² ?

a = -3² = -9
b = -2³ = -8
c = -(-4)² = -16

A+B-C = -9 + (-8) - (-16) = -9 -8 +16=-17 +16 = -1
 x = (1/9) ^A+B-C --->. x= (1/9)-¹--> x = 9¹ --> x = 9

x-¹/² = 9-¹/² = (1/9)² = 1/81
