Question

am nevoie de ajutor ​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

=3⁴⁵:[(3⁴⁴*(1+1+1)] +2³⁰:[2²⁹*(1+1)]

=3⁴⁵: (3⁴⁴*3)+2³⁰:(2²⁹*2)

=3⁴⁵:3⁴⁵+2³⁰:2³⁰

=1+1

=2

-

b)

=(2²⁸+6¹⁰):(6¹⁰+2²⁸)

= 1

-

c)

5⁷:5⁶+{[2⁴*(2²)²³:(2³))³)⁵]+2⁶( 19-9 *5²¹:5²¹) }:112

= 5 + { [ 2⁴*2⁴⁶:2⁴⁵+2⁶*(19-9*1)} :112

= 5+ [( 2⁵⁰:2⁴⁵)+2⁶*10] :112

= 5+ ( 2⁵+2⁶*10) :112

= 5+ (32+64*10):112

= 5+ ( 672:112)

= 5+ 6

= 11

d)

a)

=366: {[(8*3)⁵:2¹⁵:3⁴+(3²)¹⁷: (3²)¹⁶* [ 100:5 - ( 2⁵)⁶*2⁸-(2²)¹⁹)*5]}

=366: { [ (2³)⁵*3⁵:2¹⁵:3⁴+3³⁴:3³²*[20 - ( 2³⁰*2⁸-2³⁸)*5 }

= 366: [(2¹⁵*3⁵:2¹⁵:3⁴+3²*(20- (2³⁸-2³⁸)*5]

=366: [ (2¹⁵:2¹⁵*3⁵:3⁴+3²*(20 - (0*5)]

=366: [ ( 1*3+9*(20-0]

=366: (3+9*20)

=366:(3+180)

=366:183

= 2
