Answer 1

1. a) (2⁹)⁴÷2³⁴×2³-3³ = 2³⁶÷2³⁴×2³-3³ = 2⁵-3³ = 32-27 = 5

b) 2022¹+0¹⁰²+1⁵¹⁶+1856⁰ = 2022+0+1+1 = 2024

c) 3^3^1^8 + 5^2^1 = 3³+5² = 27+25 = 52

d) 9²⁰÷(3×3³×3⁵)⁴-3³-3⁰ = 3⁴⁰÷(3⁹)⁴-3³-3⁰ = 3⁴⁰÷3³⁶-3³-3⁰ = 3⁴-3³-3⁰ = 81-27-1 = 53

2. a) 1156+1156×1471-156×1472 = 1156(1471+1)-156×1472

= 1156×1472-156×1472 = 1472(1156-156) = 1472×1000 = 1472000

b) 4a+5b=144 |•3

2b+3c=45 |•2

=>

12a+15b=432

4b+6c=90

________ +

12a+19b+6c=522

3.

a) (7²⁸)⁵ si (7³)⁴⁷ <=> 7¹⁴⁰ < 7¹⁴⁹

b) 5³⁰⁰ si 11²⁰⁰ <=> 125¹⁰⁰ > 121¹⁰⁰
