Question 467119
write these as the logarithm of a single expression... 
log(x^2+3x-10)-log(x+5)
---
= log[(x^2+3x-10)/(x+5)]
----
= log[(x+5)(x-3)/(x+5)]
---
= log(x-3)
==========================================

3log(2x^2)-(1/2)log(16x^4)
---
= log[(2x^2)^3/sqrt(16x^4)]
----
= log[8x^6/4x^2]
---
= log[2x^4]
====================
 
-2log(P)+(1/3)log(R)
---
= log[P^-2 * R^1/3)]
---
= log[cbrt(R)/P^2]
=========================
