Ajutor !!!!!!!!​ Ajutați mă cat mai repede va rog dau coroana

Answer 1

Explicație pas cu pas:

b)

{1²+2³•[3⁴-4⁵:2⁴-(2²)²]}:3²+10⁰-0¹⁰=

= {1+8•[81-4⁵:4²-4²]}:9+1-0

= {1+8•[81-4³-16]}:9+1

= {1+8•[81-64-16]}:9+1

= {1+8•1}:9+1

= {1+8}:9+1

= 9:9+1

= 1+1 = 2

c)

(25³)⁴:(3²+4²)¹⁰-0³•3⁰+(4•6)²-(5²)²=

= 25¹²:(9+16)¹⁰-0•1+24²-25²

= 25¹²:25¹⁰-0+24²-25²

= 25²+576-25²

= 576

d)

81⁵:3¹⁹•3²-3²+27²•3²⁷:81⁶:9³=

= (3⁴)⁵:3¹⁹•3²-3²+(3³)²•3²⁷:(3⁴)⁶:(3²)³

= 3²⁰:3¹⁹•3²-3²+3⁶•3²⁷:3²⁴:3⁶

= 3•3²-3²+3³³:3²⁴:3⁶

= 3•9-9+3⁹:3⁶

= 27-9+3³

= 18 + 27

= 45
