Yes.
Is it correct to speak this way?
1) Could you please help me take a look?
2) I was wondering if you could help me take a look.
Yes.
They are both perfectly acceptable grammatically although not entirely clear in meaning. Do you want someone else to take a look in order to help you, or do you want to take a look but need someone's help to do so?
Your thread title, however, does not follow the forum guidelines. You should include some or all of the words you are querying. A good title for this thread would have been "Could you please help me to take a look?"
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
[QUOTE=emsr2d2;955851]They are both perfectly acceptable grammatically although not entirely clear in meaning. Do you want someone else to take a look in order to help you, or do you want to take a look but need someone's help to do so?
So, which one is correct?
"Could you help me take a look?"
or
"Could you help me to take a look"
Further to the above, I'm not too sure when i should add in "to"
For example:
"Could you help me cook?" or "Could you help me to cook?"
"Could you help me carry my books?" or "Could you help me to carry my books?"
Is there a difference between the sentences?

Regarding the thread title, and apart from the valid comment by bobk:
It should be Are these sentences correct? You cannot say Are this sentences.
