Penjelasan dengan langkah-langkah:
[tex]\sqrt{33} \times \sqrt{22} \times \sqrt{11} [/tex]
[tex] = \sqrt{33 \times 22 \times 11} [/tex]
[tex] = \sqrt{7.986} [/tex]
[tex] = \sqrt{ {11}^{2} \times 66} [/tex]
[tex] \bf = 11 \sqrt{66} [/tex]
[tex]~[/tex]
[tex]2 \sqrt{11} + 2 \sqrt{44} + \sqrt{11} [/tex]
[tex] = 2 \sqrt{11} + 2 \sqrt{ {2}^{2} \times 11 } + \sqrt{11} [/tex]
[tex] = 2 \sqrt{11} +( 2 \times 2) \sqrt{11} + \sqrt{11} [/tex]
[tex] = 2 \sqrt{11} + 4 \sqrt{11} + \sqrt{11} [/tex]
[tex] = (2 + 4 + 1) \sqrt{11} [/tex]
[tex] \bf = 7 \sqrt{11} [/tex]
[tex]~[/tex]
[tex]\displaystyle \frac{1}{x} - \frac{1}{y} [/tex]
[tex] \displaystyle= \frac{1 . y}{x.y} - \frac{1.x}{x.y} [/tex]
[tex]\displaystyle = \frac{y}{xy} - \frac{x}{xy} [/tex]
[tex]\displaystyle \bf = \frac{y - x}{xy} [/tex]

Jawab:
1. 11√66
2. 7√11
3. (y-x)/xy
Penjelasan dengan langkah-langkah:
1. √(11x3) x √(11x2) x √(11)
= √3 x √2 x √11 x √11 x √11
= √3 x √2 x √11 x √(11)^2
= √(3x2x11) x 11
= 11√66
2. 2√11 + 2√(11x4) + √11
=2√11 + 2x2√11 + √11
=2√11 + 4√11 + √11
=7√11
3. /susah ngetiknya huhu/
1/x - 1/y
=y/xy - x/xy
=(y-x)/xy
