nilai dari [tex] \frac{3}{ \sqrt{3 + \sqrt{2} } } \: [/tex]adalah?
Answer (4)
Mary: x yrs old Mike: 3x yrs old
In four yrs:
Mary: x+4 yrs old Mike: 3x+4 yrs old
As the text of task:
3x+4=2(x+4) 3x+4=2x+8 3x-2x=8-4 x=4
Mary is 4 yrs old
x-the age of Mike y-the age of his sister
x=3y
x+4=2(y+4) 3y+4=2y+8 3y-2y=8-4 y=4 years
x=3*4=12 years
Mary is currently 4 years old. We determined this by setting up an equation based on their ages and solving for x. The calculations show that in 4 years, Mike will indeed be twice Mary's age.

Jawaban:3(√3 - √2) Penjelasan dengan langkah-langkah:rasionalkan terlebih dahulu :[tex] \frac{3}{ \sqrt{3 + \sqrt{2} } } \times \frac{ \sqrt{3 - \sqrt{2} } }{ \sqrt{3 - \sqrt{2} } } [/tex]lalu operasikan :[tex] = \frac{3( \sqrt{3} - \sqrt{2} }{3 - 1} = \frac{3( \sqrt{3} - \sqrt{2)} }{1} [/tex]didapatkanlah hasilnya :[tex] 3( \sqrt{3} - \sqrt{2)} [/tex]
