sorry... i know this is a lame question but... to write an expression as a positive exponent should i just change the negative exponent to a positive one?
for example..
7^2 would just be 7^2
right?

Best ResponseYou've already chosen the best response.0You would move it to the denominator to make the exponent positive: \[a^{n}=\frac{1}{a^n}\rightarrow 7^{2}=\frac{1}{7^2}\]

Best ResponseYou've already chosen the best response.0Oh okay so basically you just put it under 1 with the positive exponent?

Best ResponseYou've already chosen the best response.0yeah but sometime you end up with a reversed scenario such as: \[\frac{1}{5^{3}}\] in this case you would move it to the numerator to make it positive \[\frac{1}{5^{3}}\rightarrow 5^3\]

Best ResponseYou've already chosen the best response.0ah cool thanks :D but i have another question XD... what if for example you have... ab^2c or something like x^2y^3? i have similar problems further along but figured id ask now x]

Best ResponseYou've already chosen the best response.0Is the first one \[(ab)^{2c}, or, ab^{2c}\]

Best ResponseYou've already chosen the best response.0its \[ab ^{2}c\] and \[x ^{2}y ^{3}\]sorry forgot about the equation button

Best ResponseYou've already chosen the best response.0in the case of \[ab^{2c}\] only b is raised to the negative exponent of 2c, so you would move b to the denominator\[ab^{2c}=\frac{a}{b^{2c}}\] in the case of \[x^{2}y^{3}\] both x and y are raised to a negative exponent, so you would move both of them to the denominator\[x^{2}y^{3}=\frac{1}{x^2y^3}\]

Best ResponseYou've already chosen the best response.0well the c isnt part of the b^2 exponent its like b^2 and c alone

Best ResponseYou've already chosen the best response.0oh, sorry.... well then b will move to the denominator bc it carries a negative exponent\[ab^{2}c=\frac{ac}{b^2}\]
