Question

mate clasa a 5 a va rog repede ​

Answer 1

Răspuns:

a=>2¹⁸²–2¹⁸³–2¹⁸⁴

b=>2•3⁹¹–2•3⁹²–2•3⁹³–3⁹⁴

c=>7⁹³+9•7⁹²+9•7⁹¹

Answer 2

Răspuns:

2¹⁸⁴-2¹⁸³-2¹⁸²=2¹⁸²×(2²-2¹-2⁰)=2¹⁸²×(4-2-1)

=2¹⁸²×1=2¹⁸²

3⁹⁴-2×3⁹³-2×3⁹²=3⁹²×(3²-2×3¹-2×3⁰)=3⁹²×(9-2×3-2×1)

=3⁹²×1=3⁹²

7⁹³+9×7⁹¹-8×7⁹²=7⁹¹×(7²+9×7⁰-8×7¹)=7⁹¹×(49+9×1-8×7)

=7⁹¹× 2=14⁹¹

2¹⁸²,3⁹²,14⁹¹(in ordine crescatoare)

(la ultima nu sunt sigura daca e asa)
