Question

2) Se A = ( - 7 ) -² e B = 35 (elevado a 0) , calcule :
(A) A+B
(B) B . 2 A
(C) A : B
(D) A . B
(E) A - B

Answer 1

A= (-7)-²
A= (-1/7)²
A= + 1/49

B=35°
B= 1

A) A+B= 1/49+1= 1+49/49= 50/49

B)B.2A= 1.2.1/49= 2/49

C)A:B= 1/49:1= 1/49

D)A.B= 1/49.1= 1/49

E)A-B= 1/49-1= 1-49/49= -48/49
