hi.
sorry for this bad news - we haven't went to do the shirt yet, i'm so sorry. i know it's been dragging for 3 months already, and argh, we could have done it during the holidays right -.-
we have really really little time now, and we're still trying to fit our timings ): & what's worse is there's always something on everyday after school, and everything clashes. shit, really really very sorry okay. D:
it's commontest week now, so it's even more impossible. give us some time, after commontests, promise :) this is dumb, it's like the
lang lai le story now. believe us one more time okay! :)
i hope y'all are not very desperate for the section tee, or else y'all can come haunt us with a chopper =/

Given that lg X = p , lg Y = q , express the following in terms of p and q:
1) lg (y ^ x)
2) xy
3) lg [(100x^half) divide by (y^2)]
4) lg (10yx^3)^half
X=10^p Y= 10^q
1) lg (y^x) = xlg y = q10^p
2) xy = (10^p)(10^q) = 10^pq
3) lg [(100x^half divide by (y^2)] = lg (100x^half) - lg y^2
= lg 100 + lg x^half - lg y^2
= lg 10^2 + half lg X - 2lg y
= 2 + half p - 2q
4) lg (10yx^3)^half = half lg (10yx^3)
= half [lg 10 + lg y + lg x^3]
= half [1 + q + 3p]
that's the answer to those 4 questions. if there are any problems or mistakes, please let me know. i hope i got the answers correct.
jiayou for common test!!!

hi everyone :)
jy for common tests!
someone tell me how to do this pleaseeeee
Given that lg X = p , lg Y = q , express the following in terms of p and q
:
- lg (y ^ x)
- xy
- lg [(100x^half) divide by (y^2)]
- lg (10yx^3)^half
* I know it looks horrible to understand here but erm, at least the first and second one can?
