[tex] \sqrt{98} - \sqrt{2} + \sqrt{32} = ....[/tex]
.......
Penyelesaian:
√98-√2+√32
=√2×49-√2+√2×16
=7√2-√2+4√2
=(7-1+4)√2
=10√2
=√200

Penjelasan dengan langkah-langkah:
[tex]\sf \sqrt{98} - \sqrt{2} + \sqrt{32}[/tex]
[tex]\sf = \sqrt{ {7}^{2} \times 2} - \sqrt{2} + \sqrt{ {2}^{5} } [/tex]
[tex]\sf = 7 \sqrt{2} - \sqrt{2} + \sqrt{ {2}^{4} } [/tex]
[tex]\sf = 7 \sqrt{2} - \sqrt{2} + {2}^{2} \sqrt{2} [/tex]
[tex]\sf = 7 \sqrt{2} - \sqrt{2} + 4 \sqrt{2} [/tex]
[tex]\sf = (7 - 1 + 4) \sqrt{2} [/tex]
[tex]\sf = (6 + 4) \sqrt{2} [/tex]
[tex]\sf = 10 \sqrt{2} [/tex]
