Given that `x= (sqrt3 sqrt2) /(sqrt3 sqrt2)` and `y = (sqrt3 sqrt2) /(sqrt3 sqrt2)` We need to find `x^2 xy y^2` Now we will rationalize xWe know that rationalization factor for `sqrt3sqrt2` is `sqrt3sqrt2` `sqrt3sqrt2`We will multiply numerator and denominator of the given expression `x= (sqrt3 sqrt2) /(sqrt3 sqrt2)` by `sqrt3 sqrt2`, to get.

7 Since n3 < n3 2, we have √ nln(n) n3 2 < √ nln(n) n3 Furthermore, because ln(n) < n for all n > 0 1, we obtain √ nln(n) n3 2 < √ nn n3 = n−3/2 Now, the series P n−3/2 converges (it’s a pseries with p = 3/2 > 1) and hence the comparison test implies that the series P √ nln(n) n32 also converges 1If f(x) = lnx x, then f. √ B2 Example 8 Express 3sinα4cosα in the above form From what we saw above, 3sinα4cosα = 32 42 sin(αβ) =5sin(αβ) where sinβ = 4 5 and cosβ = 3 5 Since both sinβ and cosβ are positive, β should be in the first quadrant Using a calculator, we find that β ≈ 531 Thus, 3sinα4cosα =5sin(α531) 22 Double and.  So if we average them to get a new starting point x ′, the new pair ( x ′, 2 / x ′) will be closer to √2 than the first one 1 Start with any positive number x 2 Calculate 2 / x 3 Take the average of x and 2 / x 4 Repeat steps 2 and 3 until satisfied.
