How to live smart

In this sentence, what is the word class of 'smart'? Is it an adjective or an adverb?
Its form is an adjective, but grammartically, an adjective can not cannot be put after 'live'.
I'm confused about this.
plz Please let me know.

Before worrying about what type of word "smart" is in that sentence, please see my amendments to your post in red.

Your posts on here will be much easier to read if you concentrate on certain aspects of written English. You will get more responses if you:

1) Capitalise the first word of every sentence.
2) Use articles.
3) "Cannot" is all one word.
4) Please don't use textspeak (plz, thx, u etc) - use complete words.

As far as your question is concerned, you are right that "to live" would normally be followed by an adverb (as would any other verb). However, stylistically, there are a lot of phrases which don't follow that rule. They tend to be "slogan" style phrases.

Live smart.
Eat healthy.
Buy clever.

Grammatically, they should be "Live intelligently", "Eat healthily" and "Buy cleverly/intelligently" but they've become recognised in this form instead. I suppose you could say, for example, that "Live in a smart way" has been abbreviated but even so "in a smart way" = "smartly/intelligently".

My only advice is that some things which don't follow normal grammatical structure are used every day and by many people. That does not mean they should be used by students or learners, especially in work that is to be submitted for marking.

And, to top it all, it's not a sentence. Neither is "How to live smartly."

(1) Please remember Apple's famous slogan: Think different.

(2) Mr. Steve Jobs said that he wanted "different" to be an adjective, such as

in "Think big,"

(3) Yes, I believe that we can parse "smart" in your example as an adjective.

That's true, although if it were the title of an article/essay etc it would be acceptable.

Yes, but I interpreted
"how to live smart

as an implication that the OP, at least, was assuming it was a sentence.
