Explicație pas cu pas:
a)
=(7²²*7³):[7²³*(1+(6²)¹²:6²³)]
= 7²⁵:[ 7²³*(1+6²⁴:6²³)]
= 7²⁵: [7²³*(1+6)]
=7²⁵:(7²³*7)
=7²⁵:7²⁴
= 7

b)
=[(3-(2²)¹⁵:(2³)¹⁰) *(2⁴)²) ]:[2*2²*(2²)²]³
= [(3-2³⁰:2³⁰)*2⁸] :(2*2²*2⁴)³
={[(3-1)*2⁸]*2⁸} : (2⁷)³
= (2⁸*2⁸*2⁸):2²¹
= 2²⁴:2²¹
=2³
=8

c)
={5²¹:[(1+(2³)¹⁰:(2²)¹⁴]¹⁹-1} :[ (2²)¹⁵:(2³)⁹]
= { 5²¹: [ (1+2³⁰:2²⁸)¹⁹-1 } : (2³⁰:2²⁷)
= [ 5²¹:(1+2²)¹⁹-1 } : 2³
= [5²¹:(1+4)¹⁹-1] :2³
= (5²¹:5¹⁹-1):2³
= (5²-1):2³
= (25-1) :8
= 24 :8
= 3
-
d)
= [(7-2⁵*(2³)⁷: (2²)¹³):3+1 ]⁴⁹ : [( 3²)²)³]⁴
= [ (7-2⁵*2²¹:2²⁶) :3+1 ]⁴⁹ : 3⁴⁸
= [ (7- 2²⁶:2²⁶):3+1]⁴⁹:3⁴⁸
= [( 7-1) :3+1]⁴⁹:3⁴⁸
= (6:3+1 )⁴⁹:3⁴⁸
= (2+1)⁴⁹:3⁴⁸
=3⁴⁹:3⁴⁸
= 3
