Algm pode me ajudar ?

Answer 1

Resposta passo a passo:

A) (1 1/4)^2+(0,25)^2

(4/4 + 1/4)^2+(1/4)^2

[(4+1)/4)^2+(1/4)^2

(5/4)^2+(1/4)^2

5^2/4^2+1^2/4^2

25/16+1/16

(25+1)/16

26/16

13/8

B) (-0,25)^2÷(-0,75)^2

(-1/4)^2÷(-3/4)^2

(-1)^2/4^2÷(-3)^2/4^2

1/16÷9/16

1/16×16/9

(1×16)/(16×9)

(1×1)/(1×9)

1/9

C) (1/4)^-1×(-1/8)^0

(4/1)^1×(-1)^0/8^0

4^1×(1/1)

4×1
