Answer 1

Răspuns:

Explicație pas cu pas:

b) {1²+2³·[3⁴-4⁵:2⁴-(2²)²]}:3²+10⁰-0¹⁰={1+2³·[3⁴-2¹⁰:2⁴-2⁴]}:3²+1-0=  

[1+2³(3⁴-2⁶-2⁴)]:3²+1= [1+2³(81-64-16)]:3²+1=(1+8·1):3²+1=9:9+1=1+1=2

c) (25³)⁴:(3²+4²)¹⁰-0³·3⁰+(4·6)²-(5²)²=5²⁴:25¹⁰-0·1+24²-5⁴=5²⁴:5²⁰+24²-5⁴=  

5⁴+24²-5⁴= 24²=576

d) 81⁵:3¹⁹·3²-3²+27²·3²⁷:81⁶:9³=(3⁴)⁵:3¹⁹·3²-3²+(3³)²·3²⁷:(3⁴)⁶:3⁶=

3²⁰:3¹⁹·3²-3²+3⁶·3²⁷:3²⁴:3⁶ = 3·3²-3²+3³³:3²⁴:3⁶=

27-9+3⁹:3⁶=18+3³=18+27=45
