Penjelasan dengan langkah-langkah:
[tex] \sqrt{ {a}^{2} } = ({ \sqrt{a}})^{2}[/tex]
Bukti:
misalkan a = 3
[tex] \sqrt{ {a}^{2} }=\sqrt{ {3}^{2} } [/tex][tex] = \sqrt{9} = 3[/tex]
[tex]({ \sqrt{a}})^{2} = ({ \sqrt{3}})^{2}[/tex]
[tex] = \cancel{\sqrt{3}}^{2} = 3[/tex]
Jadi, pernyataan [tex] \sqrt{ {a}^{2} }=\sqrt{ {a}^{2} } [/tex] Benar
