√2 (√45 + √80) can be written in the form a√10 where a is an integer. Find the value of a.
aleksandrvk [35]

Answer:

a = 7

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

\sqrt{2} (\sqrt{45} + \sqrt{80} ) ← distribute parenthesis by \sqrt{2}

= \sqrt{90} + \sqrt{160}

= \sqrt{9(10)} + \sqrt{16(10)}

= \sqrt{9} × \sqrt{10} + (\sqrt{16} × \sqrt{10} )

= 3\sqrt{10} + 4\sqrt{10}

= 7\sqrt{10} → in the form a\sqrt{10}

with a = 7

Can someone explain HOW to simplify this algebraic fraction, as in tell me why and what I need to do for each step : 1-n/n^2-1
Andreyy89

- I’m assuming the expression implies the following:

(1-n)/(n^2 - 1)

The steps goes as follows:

= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)

At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.

= -1/(n+1) , which is the answer

Note: You could also see it as 1/-(n+1) or 1/(-n-1)
