(√7 +√4) (√7 + √4) pakai cara kak
![]()
Jawaban:
[tex]( { \sqrt{7} })^{2} + \sqrt{4 \times 7} + \sqrt{4 \times 7} + ( { \sqrt{4} )}^{2} [/tex]
[tex] = 7 + \sqrt{28} + \sqrt{28} + 4[/tex]
[tex] = 11 + 2 \sqrt{28} = 11 + 2 \sqrt{ {2}^{2} \times 7 } [/tex]
[tex] = 11 + 2 \times 2 \sqrt{7} = 11 + 4 \sqrt{7} [/tex]
Penjelasan dengan langkah-langkah:
[tex] \sqrt{a} \times \sqrt{a} = a [/tex]
[tex] \sqrt{a} \times \sqrt{b} = \sqrt{a \times b} [/tex]
