Question 222986: I cannot figure this out. I have tried and tried. I hope you can help me.
Express as a single term that does not contain a logarithm: e^ln8x^5-ln2x^2
everything after the e is the exponent
Thank you

e^ln8x^5-ln2x^2
= e%5E%28ln%288x%5E5%29+-+ln%282x%5E2%29%29
=e%5E%28ln%284x%5E3%29%29
= 4x%5E3

Express as a single term that does not contain a logarithm: e^ln8x^5-ln2x^2
everything after the e is the exponent
-----------------------------------------
e^ln8x^5-ln2x^2
---
= e^[ln(8x^5/2x^2)]
---
= e^[ln(4x^3)]
---
= 4x^3
================
That last step is the way it is because e^(ln(b)) = b
