In this problem: 1/(3x/5)^2
I solved:
1/1*(5/3x)^2
1/1*(25/9x)^2
25/9x^2
is this right?

I'm going to guess you mean that you "simplified". If so, this first step is correct.gracierox77 said:In this problem: 1/(3x/5)^2 I solved: 1/1*(5/3x)^2
How did you go from "(5/3x)<sup>2</sup>" to "(25/9x)<sup>2</sup>"? Why did the 5/3 turn into a 25/9, while the x and the squaring stayed the same?gracierox77 said:1/1*(25/9x)^2
If, in your previous step, you mean "(25/(9x<sup>2</sup>))" then, yes, this is okay. But otherwise, two "wrongs" have somehow "cancelled out" and magically produced a "right". This may not get credit now, and will almost certainly cause grave difficulties later (such as on tests).gracierox77 said:25/9x^2
