so i'm doing review from last year and i can't remember how to do this question. It seems pretty straight forward but i don't want to just keep doing them the wrong way so if the pit can help me it's all good. The question is :

Simplify:

4

Simplify:

__6 + (radical 32)__4

#2

24576?

I can't remember this stuff...

Edit: According to my calculator I was way off...

38/16?? EDIT: 19/8?

oh and btw its called the teh mathz threadz TS

searchbars are helpful

#4

6+2(radical)4 / 4

Since a radical = X * number inside radical ^2

Since a radical = X * number inside radical ^2

why do people keep asking the pit for math help? dont you have any Asian friends?

yes but they're sleeping

I tried asking Ex'sAndOh's

He didn't help me at all

The correct answer is

(3/2) + (radical 2)

You get that by...

Square root of 32 = 2 x 2 x 2 x 2 x 2

Since there are 2 groups of two, you take a "2" out for each, leaving only one "2" behind. The two "2"s you take out multiply and you get 4. So then you get

6 + 4x(radical 2) / 4

6/4 = 3/2

4x(radical 2) / 4 = radical 2

final answer is (3/2) + radical 2

(3/2) + (radical 2)

You get that by...

Square root of 32 = 2 x 2 x 2 x 2 x 2

Since there are 2 groups of two, you take a "2" out for each, leaving only one "2" behind. The two "2"s you take out multiply and you get 4. So then you get

6 + 4x(radical 2) / 4

6/4 = 3/2

4x(radical 2) / 4 = radical 2

final answer is (3/2) + radical 2

hold up i thought you couldn't reduce the expressions unless they are multiplication or division, not addition or subtraction

Right. But that first expression (the problem you are solving) is the same thing as 6/4 + (radical 32) / 4. You can separate the 4 and place it under each of the terms that have a "+" or "-" between them. When you finally simplify the radical, the "4" out in front cancels.

I can confirm this.

It's the same as (x + y)/3 = x/3 + y/3

I can confirm this.

It's the same as (x + y)/3 = x/3 + y/3

Yes sir. Thing about it. Go from one to the other. The denominators are the same, so therefore they can be added, or subtracted.
