[tex] \sqrt{25} \times \sqrt{9} + \sqrt{100} - \sqrt{81} = \\ = \sqrt{ {5}^{2} } \times \sqrt{ {3}^{2} } + \sqrt{ {10}^{2} } - \sqrt{ {9}^{2} } \\ = 5 \times 3 + 10 - 9 \\ = 15 + 10 - 9 \\ = 25 - 9 \\ = 16[/tex]
Penjelasan dengan langkah-langkah:
= √25 × √9 + √100 - √81
= √5² × √3² + √10² - √9²
= 5 × 3 + 10 - 9
= 15 + 10 - 9
= 16
