Answer: 
Step-by-step explanation:
Given the following expression shown in the picture:

You need to use a process called "Ratinalization".
By definition, using Rationalization you can rewrite the expression in its simplest form so there is not Radicals in its denominator.
Then, in order to simplify the expression, you can follow the following steps:
<em>Step 1</em>. You need to multiply the numerator and the denominator of the fraction by
, which is the conjugate of the denominator
.
<em>Step 2</em>. Then you must apply the Distributive property in the numerator.
<em>Step 3</em>. You must apply the following property in the denominator:
Therefore, applying the procedure shown above, you get:

<em>Step 4</em>. You can observe that the expression can be simplified even more. Since:

You get:

150; because 6-11 is almost 180, but it’s not quite there, so it’s a little less

Answer:
$47,200
Step-by-step explanation:
Given :
The total income of a married couple = $75,000.
Number of children = 2
Therefore to find the taxable income of a U.S. family is given by the following formula ---
taxable income = total income- exemption deduction - standard deduction
We know that exemption deduction for a U.S couple as fixed by the government is $15,600.
And the standard deduction for a U.S couple as fixed by the government is $12,200.
Thus in order to find the taxable income of the couple, use the formula
taxable income = total income- exemption deduction - standard deduction
= $75,000 - $15,600 - $12,200
= $47,200.
Thus the taxable income is $47,200.
