Question

Determine o valor da expressão a) 8^0+16÷(-2)^3-5.(-1)^3 b)raiz de 100-raiz de 64 c) raiz de 4 + raiz de 400 - 2.(-10)^2 d) 20+3raiz de 25 + raiz de 64 e)raiz de 9 - 4raiz de 49 f)(raiz de 144 + raiz de 256)-(raiz de169+raiz de 121) pfv me ajudem.

Answer 1

a) 8^0+16÷(-2)^3-5.(-1)^3=
1+16÷(-8)-5.(-1)=
1-2+5=
4

b)raiz de 100-raiz de 64=
√100-√64=
10-8=
2

c) raiz de 4 + raiz de 400 - 2.(-10)^2=
√4+√400-2.100=
2+20-200=
-178

d) 20+3raiz de 25 + raiz de 64=
20+3√25+√64=
20+3.5+8=
20+15+8=
43

e)raiz de 9 - 4raiz de 49=
√9-4√49=
3-4.7=
3-28=
-25

f)(raiz de 144 + raiz de 256)-(raiz de169+raiz de 121)=
(√144+√256)-(√169+√121)=
(12+16)-(13+11)=
(28)-(24)=
28-24=
4
