Answer 1

Răspuns:

i) 2¹⁰⁰: [ 2⁹⁸+(2²⁵)⁵:2²⁷+(5¹-3)⁹⁰·2⁸+2⁹⁸=

2¹⁰⁰:( 2⁹⁸+2¹²⁵:2²⁷+2⁹⁰·⁸+2⁹⁸)=

2¹⁰⁰:(2⁹⁸+2⁹⁸+2⁹⁸+2⁹⁸)=

2¹⁰⁰:(4·2⁹⁸)=2¹⁰⁰:(2²·⁹⁸)=2¹⁰⁰:2¹⁰⁰=1

ii) 5²⁰⁰⁴(5²-5¹-1-19)=5²⁰⁰⁴·(25-5-1-19)=5²⁰⁰⁴·0=0

iii) 2002²⁰⁰¹(2002-2001):2002²⁰⁰¹=

   2002²⁰⁰¹·1:2002²⁰⁰¹=1

iv) 5¹⁴⁰:(5²)⁷⁰+(2³)³²: (2⁴)²⁴+(10²)²⁵:10⁴⁸-2²·5²=

    5¹⁴⁰:5¹⁴⁰+2⁹⁶: 2⁹⁶++10⁵⁰: 10⁴⁸- (2·5)²=

   1++1+10²-10²=2

v)2²⁰⁰³( 2²-2-1):2³:(2⁴)⁵⁰⁰+1=

  2²⁰⁰³(4-3):2³:2²⁰⁰⁰+1= 2²⁰⁰⁰:2²⁰⁰⁰+1=1+1=2

vi) [(3⁴)⁸+(3²)¹⁶]: [(3²)¹⁵+(3³)¹⁰+3³⁰·7=

  (3³²+3³²):(3³⁰+3³⁰+3³⁰·7=

  2·3³²:3·3³⁰·7=2·3³²:3³¹·7=2·3·7=42
