Simplify $\frac{1+\sqrt{2}}{2+\sqrt{3}}$. Your solution can be converted to the form $A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})$, where

Zina [86]

Answer:

A+B+C+D = 13

Step-by-step explanation:

The given expression is:

$\dfrac{1+\sqrt{2}}{2+\sqrt{3}}$

We have to simply it and express it in the form of:

$A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})$

Multiply and divide the given expression with $2-\sqrt 3$ :

$\dfrac{1+\sqrt{2}}{2+\sqrt{3}} \times \dfrac{2-\sqrt 3}{2-\sqrt 3}\\\Rightarrow \dfrac{(1+\sqrt{2}) \times (2-\sqrt 3)}{(2+\sqrt{3})\times (2-\sqrt 3)}\\\Rightarrow \dfrac{2+2\sqrt2-\sqrt3-\sqrt6}{2^2-(\sqrt{3})^2}\\\Rightarrow \dfrac{2+2\sqrt2-\sqrt3-\sqrt6}{4-3}\\\Rightarrow \dfrac{2(1+\sqrt2)-(\sqrt3+\sqrt6)}{1}\\\Rightarrow 2(1+\sqrt2)-(\sqrt3+\sqrt6)$

It is the simplified form of given expression.

<u>Formula used: </u>

<u></u> $(a+b)(a-b) = a^{2} -b^{2}$ <u></u>

<u></u>

<u>Comparing the simplified expression with </u> $A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})$ <u></u>

$2(1+\sqrt2)-(\sqrt3+\sqrt6)=A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})\\\Rightarrow A =2, B=2, C=3\ and\ D=6$

So, value of

$A+B+C+D = 2+2+3+6 = 13$

Eduardwww [97]

Answer: 15.56%

Step-by-step explanation:

Given : Your checking account balance is $225.

i.e. Account balance= $225

You received a “bounced” check and your bank has charged you a penalty fee of $35.

i.e.Penalty fee= $35

Now, the percent of your balance the penalty cost :-

$\dfrac{\text{Penalty fee}}{\text{Account balance}}\times100\\\\=\dfrac{35}{225}\times100=15.5555555556\approx15.56\%$

Hence, the penalty cost 15.56% of your balance .
