Răspuns:

Explicație pas cu pas:

a)

=[3⁵⁷:(3²)²⁵*3¹⁰):3¹⁵

= (3⁵⁷:3⁵⁰*3¹⁰):3¹⁵

= (3⁷*3¹⁰):3¹⁵

= 3¹⁷:3¹⁵

=3²

=9

-

b)

=(3³⁶:3³²-56):5

= (3⁴-56):5

= (81-56):5

=25:5

=5

-

c)

=[(3*4)²⁴-(2*6)²⁴]:12+2⁶

=(12²⁴-12²⁴):12+2⁶

= 0:12+2⁶

= 0+ 64

= 64

-

d)

= [3²⁶*(4*3²-5)]:31

=[ 3²⁶*(4*9-5):31

= 3²⁶*31:31

= 3²⁶*1

=3²⁶
