b) =(2⁴)⁵:(2³)⁶+[(2²)⁸·(3³)⁵]:[(2³)⁵·(3²)⁷]
=2²⁰⁻¹⁸+(2²ˣ⁸·3³ˣ⁵):(2¹⁵·3¹⁴)
=2²+2¹⁶:2¹⁵·3¹⁵:3¹⁴
=4+2¹⁶⁻¹⁵·3¹⁵⁻¹⁴
=4+2·3=4+6
=10
__________
c) =(3⁴)⁴:(3³)³-7·[278·(2941-2595)-345·(5699-5421)
=3¹⁶⁻⁹-7·(278·346-345·278)
=3⁷-7·(96188-95910)
=3⁷-7·278
=2187-1946
=241
_________
d) = 8³ˣ²:(2³·2⁵)²+2⁴·2⁶·(2³)³+2⁵·2²:2⁴
=8⁶:(2³⁺⁵)²+2⁴⁺⁶⁺⁹+2⁵⁺²⁻⁴
=(2³)⁶:(2⁸)²+2¹⁹+2³
=2¹⁸⁻¹⁶+2¹⁹+2³
=2²+2¹⁹+2³
=4+2¹⁹+8
________
e) =(3²)⁷:[(3²·3⁴)²]+3⁵·(3³)²:3²ˣ⁵........
=3²ˣ⁷:(3²⁺⁴)²+3⁵·3³ˣ²:3¹⁰.....
=3¹⁴:3⁶ˣ²+3⁵⁺⁶⁻¹⁰......
=3¹⁴:3¹²+3¹....
=3¹⁴⁻¹²+3....
=3²+3.....
acesta l-am calculat cat am putut completezi tu cu ce nu se vede
