Question 1033286: 2. The expression log(3+x) is undefined for what values of x?
3. If loga = (1/3)logx - 3logy, what is the value of a?
4. If loga=h and logb=j, write the expression log(a^3/b^2) in terms of h and j.
5. If log3=s and log2=t, rewrite the expression log72 in terms of s and t.

2. log(3+x) is undefined for 3+%2B+x+%3C=+0, or x+%3C=+-3.
3. If+loga+=+%281%2F3%29logx+-+3logy ==> loga+=+logx%5E%281%2F3%29+-+logy%5E3+=+log%28x%5E%281%2F3%29%2Fy%5E3%29 ==> a+=+x%5E%281%2F3%29%2Fy%5E3.
4. log%28a%5E3%2Fb%5E2%29+=+3loga+-+2logb+=+3h+-+2j,
5. log+72+=+3log2+%2B+2log3+=+3t+%2B+2s.
