Answer 8

Saan: Have you tried evaluating any of the expressions contianed in newtextdocument7.txt? I'm curious, and would like to see what work you yourself have done there.

Regarding choice #4: \[5(\frac{ 5^{5} }{ 5^{3} })=\frac{ 5^{1}*5^{5} }{ 5^{3} }=\frac{ 5^{1+5} }{ 5^{3} }=\frac{ 5^{6} }{ 5^{3}}=5^{6-3}=5^{3}=125\]

Answer 9

Before you look at the other choices, please examine this example thoroughly and ask questions if you're not 100% sure of what I'm doing here.

Regarding #2:
1.5[5^3
___
2
_
5

I find this expression to be ambiguous. Here's my interpretation. You need to check whether I have it correctly or not:

\[\frac{ 1.5[5^{3}] }{ \frac{ 2 }{ 5} }\]

If my interpretation is correct, then please try evaluating this expression.

Please try evaluating #2 and #3 also.

Once I've seen your work, I'll gladly give you more feedback.
