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
