i am gived up to try several time but it dosent work
is there any one to help me?

Either the tarball is corrupt (is there a checksum to verify?), or the file name extension lies. In any case, you can expand a compressed tarball without decompressing the file first with tar using either the -z (gzip) or -j (bzip2) options: tar -zxf tarballname, or tar -jxf tarballname. This is useful especially in situations where you are running low on storage space.
