vă rog frumos repede am nevoie urgent dau coroana​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

= 5³:{[ 2⁵-( 7*2⁷):(2*7) -1)]:9}

= 5³:[ 2⁵-( 2⁶*1-1):9]

= 5³:( 2⁵ - 63:9)

=5³: (2⁵-7)

=5³:(32-7)

= 5³: 25

= 5³:5²

=5

-

b)

= 6²:{[ 4²- (5*3⁵:3*5)-1 ]: 8 }

=6²:{[ 4²-(3⁴-1)] :8 }

= 6²: [ (16-(80:8]

= 6²: (16-10)

= 6²:4

=36:4

=9

-

c)

={ 11²+[9²-(5*7³:5*7)]:8} :5²

= {11²+ [( 9²- 7²):8]}:5²

={11²+ [ (81-49 ):8 ]} :5²

= [11²+ (32:8)] :5²

= ( 11²+4):25

= (121+4) :25

= 125 :25

=5

-

d)

=3⁴:{[ 2⁷-(4*5⁵:5*4 -125 ):4 ]

= 3⁴ : {[ 2⁷- ( 5⁴*1-125) ] :4}

= 3⁴:[2⁷- (625-125) :4 ]}

= 3⁴:[(2⁷-(500:4]

=3⁴:(2⁷-125)

= 3⁴:(128-125)

=3⁴:3

= 81:3

= 27
