Answer 2

Verified answer

Jawaban:

Jumlah digit = 17 digit

Penjelasan dengan langkah-langkah:

[tex] \rm {(111.111.111)}^{2}[/tex]

[tex] = \rm (111.111.111) \times (111.111.111)[/tex]

Ingat!

11 x 11 = 121

111 x 111 = 12321

1111 x 1111 = 1234321

Maka:

[tex] = \rm (111.111.111) \times (111.111.111)[/tex]

[tex] = \rm 12345678987654321[/tex]

[tex] = \rm 12.345.678.987.654.321[/tex]

---

12345678987654321

= 12345678987654321

Banyak digit = 9 digit + 8 digit = 17 digit

Jadi, banyak digitnya adalah 17 digit.
