Answer 1

Răspuns:

a) =[(5²)⁵·5⁶·5⁰]:5¹⁰⁻⁵·5⁹=5¹⁰⁺⁶⁺⁰:5⁵·5⁹=5¹⁶⁻⁵⁺⁹=5²⁰

b) =(3²⁰·3⁸):3²⁵=3²⁸:3²⁵=3²⁸⁻²⁵=3³=27

c) =7⁵⁰:7²³⁺¹⁵⁺⁰⁺¹⁺⁹=7⁵⁰:7⁴⁸=7²=49

d) =[(2³)²:2⁷⁻⁴]·1=(2⁶:2³)·1=2⁶⁻³·1=2³=8

e) =13⁵⁺²⁺⁰⁺⁰:13²⁺⁴=13⁷:13⁶=13⁷⁻⁶=13

f) =[(3¹⁺³⁺⁶)²:3¹⁵·3]:3²=[(3¹⁰)²:3¹⁵·3]:3²=3²⁰⁻¹⁵⁺¹:3²=3⁶:3²=3⁶⁻²=3⁴=81
