AKWỤKWỌ

Akụkụ anọ ndị nwere ike ịbụ akụkụ kwụ ọtọ na akụkụ kwụ ọtọ nwere ogologo akụkụ site na 1 ruo otu na-erughị ọnụọgụ ahịrị/ogidi.

Maka nha nke square ọ bụla, chee echiche banyere akụkụ aka ekpe elu dị ka ebe mmalite. Ị nwere ike ịmepụta square niile nke nha a na grid site na ịgbanwee square mmalite a gburugburu. Ị nwere nhọrọ nke ibugharị ya gaa n'aka nri ma ọ bụ ala ọnụọgụgụ ọnọdụ ndị fọdụrụ. Ndị a bụ nhọrọ onwe ha, yabụ ị ga-enweta nke nha square ahụ.

Dịka ọmụmaatụ, were ya na ị na-agụta square abụọ site na abụọ na grid 5 site na 5 a. Enwere ike ibugharị square abụọ site na 2 n'akụkụ aka ekpe elu 1 ma ọ bụ 2 gaa n'aka nri na 1 ma ọ bụ 2 ala. Ya mere, enwere ọnọdụ atọ nwere ike ịnọ n'usoro (na-agụta ọnọdụ mbụ) na ọnọdụ atọ nwere ike ịnọ n'akụkụ kwụ ọtọ. Ya mere, enwere 3 x 3 n'ime square 1 site na 1.

Maka nsogbu grid 5 site na 5 mbụ, nke a na-enye ọnụọgụgụ square nwere akụkụ kwụ ọtọ na akụkụ kwụ ọtọ:

• 1 site na 1 square: 4 x 4 = 16
• 2 site na 2 square: 3 x 3 = 9
• 3 site na 3 square: 2 x 2 = 4
• 4 site na 4 square: 1 x 1 = 1.

E nwere ngụkọta nke 16 + 9 + 4 + 1 = 30 nwere ike ịbụ square nwere akụkụ kwụ ọtọ na akụkụ kwụ ọtọ.

Ụzọ dị mma maka square ndị fọdụrụ bụ ịnọgide na-ahazi ha n'ịgụta gị. M ga-akọwa square site n'ihe otu n'ime akụkụ ya na-eme. Dịka ọmụmaatụ, square nwere akụkụ nke na-aga otu n'aka nri na otu n'elu, ma ọ bụ square nwere akụkụ nke na-aga abụọ n'aka nri na otu n'elu - ndị a bụ square abụọ e sere na eserese a.

Iji mmịpụta agụta dịka anyị nwere na mbụ:

• 1 n'aka nri na 1 n'elu: 3 x 3 = 9
• 2 n'aka nri na 1 n'elu: 2 x 2 = 4
• 3 n'aka nri na 1 n'elu: 1 x 1 = 1
• 2 n'aka ekpe na 1 n'elu: 2 x 2 = 4
• 3 n'aka ekpe na 1 n'elu: 1 x 1 = 1
• 2 n'aka nri na 2 n'elu: 1 x 1 = 1

Ya mere, mkpokọta ya bụ: 30 (site na nke mbụ) + 9 + 4 + 1 + 4 + 1 = 49.
