Explicație pas cu pas:
a)
=3⁴²*3²:3⁴¹-5²
= 3⁴⁴:3⁴¹-5²
= 3³-5²
= 27-25
=2

b)
=2⁶*2⁹*2:2¹²-4²
=2¹⁶:2¹²-16
= 2⁴-16
= 16-16
=0

c)
=(2⁶)³:2¹⁵
=2¹⁸:2¹⁵
= 2³
= 8

d)
=5⁶*5¹²:5¹⁶-4²
=5¹⁸:5¹⁶-4²
=5²-4²
=25-16
=9

=3⁴+10*(2⁵ -2¹⁵:2¹⁴)
=3⁴+10*(2⁵-2)
=3⁴+10*(32-2)
=3⁴+10*30
= 81+300
= 381

j)
=[2³*(2²)⁷:(2³)⁵+(3³)⁶:(3²)³:3¹⁰+2+1)] :2³
= (2³*2¹⁴:2¹⁵+3¹⁸:3⁶:3¹⁰+3):2³
= (2¹⁷: 2¹⁵+3¹²:3¹⁰+3):2³
= (2²+3²+3):2³
= (4+9+3):8
=16:8
=2
