Question

va dau coroane va rog frumos exe 1 si 2 ​

Answer 1

Răspuns:

Ex 1:

a)2³+4^0-3² = 8+1-9 = 9-9 = 0

b)(8²+15²):17² = (64+225):17² = 289:17² = 17²:17² = 1

c)(2•2^5•2^15):2^18 = 2²¹:2^18 = 2³ = 8

d)(3^7)^8:3^54 = 3^56:3^54 = 3² = 9

Ex 2:

a) = 50-40:(11-300:100) =

50-40:(11-3) =

50-40:8 =

50-5 =

= 45

b) = 48+{7•[6-(4+6):5]-8}:10 =

48+[7•(6-10:5)-8]:10 =

48+[7•(6-2)-8]:10 =

48+(7•4-8):10 =

48+(28-8):10 =

48+20:10 =

48+2 =

= 50
