![]()
Materi : Bentuk Akar dan Pangkat
√25 + √9 × √( 84 - 3 )
= √5² + √3² × √81
= 5²/² + 3²/² × √3⁴
= 5¹ + 3¹ × 3⁴/²
= 5 + 3 × 3²
= 5 + 3 × 9
= 5 + 27
= { 32 }
Semoga bisa membantu

Jawaban:
32
Penjelasan dengan langkah-langkah:
[tex]\sf \sqrt{25} + \sqrt{9} \times \sqrt{(84 - 3)} = [/tex]
[tex]\sf = \sqrt{ {5}^{2} } + \sqrt{ {3}^{2} } \times \sqrt{81} [/tex]
[tex]\sf = 5 + 3 \times \sqrt{ {9}^{2} } [/tex]
[tex]\sf = 5 + (3 \times 9)[/tex]
[tex]\sf = 5 + 27[/tex]
[tex]\sf = 32[/tex]
