Question

va rog repedeeee dau coroana (sa fie cu exerxcitiile in sinea lor va rog, sa nu dati numai raspuns)​

Answer 1

B ) 3•3²•[3+3²+3³+3⁴•(3⁵-2•11²)]

3•9•[3+9+27+81•(273-2•121)]

3•9•[3+9+27+81•(273-242)]

3•9•(3+9+27+81•31)

3•9•(3+9+27+2511)

3•9•(12+27+2511)

3•9•(39+2511)

3•9•2550

27•2550=68850

C) 2²•3²•5+(4•8-5²)•3

4•9•5+(4•8-25)•3

4•9•5+(32-25)•3

4•9•5+7•3

36•5+7•3

180+21=201

D) (9³:9+9):(2³+7)-12²:72

(729:9+9):(8+7)-144:72

(81+9):15-144:72

90:15-144:72

6-2=4

E) 2•[3+4•(5+6•7)+8⁰]

2•[3+4•(5+42)+1]

2•(3+4•47+1)

2•(3+178+1)

2•(181+1)

2•182=364
