Best ResponseYou've already chosen the best response.1do you know how to "flip" \[ \frac{1}{2^{2} }\] ?

Best ResponseYou've already chosen the best response.0No, you wrote the problem statement. You did not show that you knew how to "flip" negative exponents. You could have shown that.

Best ResponseYou've already chosen the best response.1the "rule" is flip the fraction (bottom becomes top and vice versa) *and* change the exponent by multiplying the exponent by 1

phi

Best ResponseYou've already chosen the best response.1can you do that for \[ \frac{1}{2^{2}} \]

phi

Best ResponseYou've already chosen the best response.1start with \[ \frac{1}{2^{2}} \] now make the bottom (the \( 2^{2}\) ) the top and make the top (the 1) the new bottom what do you get ?

phi

Best ResponseYou've already chosen the best response.1if you had \[ \frac{a}{b}\] the flipped version is \[ \frac{b}{a} \]

Best ResponseYou've already chosen the best response.0im sorry somthing so simple is hard for me

phi

Best ResponseYou've already chosen the best response.1ok, practice with this x/y what is that flipped?

phi

Best ResponseYou've already chosen the best response.1x/y flipped becomes y/x try c/d what is that flipped?

phi

Best ResponseYou've already chosen the best response.1yes. now try 3/2 flipped is ?

phi

Best ResponseYou've already chosen the best response.1yes now this one (4*2)/(5*6) flip that

phi

Best ResponseYou've already chosen the best response.1no, (2*3)/1 just like a/b becomes b/a c/d becomes d/c x/y becomes y/x (2*3)/(4*5) becomes (4*5)/(2*3) do you see the pattern ?

phi
 one year ago
Best ResponseYou've already chosen the best response.1yes. now use that same idea on 1/(2^2) flip this one

phi

Best ResponseYou've already chosen the best response.1now when we flip things they change 1/2 is different from 2/1 but if we have 1/(2^2) and flip it to 2^2/1 then *change the exponent* so that we have 2^2/1 it turns out that \[ \frac{1}{2^{2}} = \frac{2^2}{1} \]

phi
 one year ago
Best ResponseYou've already chosen the best response.1so we do two things: flip and *change the exponent*

phi
 one year ago
Best ResponseYou've already chosen the best response.1now your problem is \[ 4 \cdot \frac{1}{2^{2}} \] and 1/2^2 is 2^2, so it is now \[ 4 \cdot 2^2 \]

phi

Best ResponseYou've already chosen the best response.12^2 means 2*2 4* 2^2 means 4*2*2
