Answer 1

Răspuns:

Explicație pas cu pas:

A={3,4,5,6,7,8,9}

B={76,77}

C={1,2,3,4,5}

D={2011,2012, 2013,........}

3⁰=1, 3¹=3, 3²=9, 3³=27, 3⁴=81, 3⁵=243>90

E={1,3,9,27,81}

0²=0,  1²=1, 2²=4, 3²=9 nu corespund deoarece x² trebuie sa fie cuprins intre 10 si 100

4²=16<100, 5²=25<100, 6²=36<100, 7²=49<100 8²=64<100, 9²=81 <100

10²=100 nu corespunde

F={4,5,6,7,8,9}

n<4, deci n poate lua valorile 0,1,2,3

n=0, x=10⁰=1

n=1, x=10¹=10

n=2, x=10²=100

n=3, x=10³=1000

G={1,10,100,1000}
