@ganeshie8 @Hero @KlOwNlOvE @radar @OOOPS
can exponents be negative @jagr2713 ?
yes
\[\sqrt[3]{1^{6}}\]
dont give me the answer. can you explain please
im reading while doing this been awhile since i did this that wasnt the answer thats what itll be when you change the exponent to positive
ohoh ik how to do it from here i think
You can use the following law to simplify the denominator: \[\large \sqrt[b]{a}=x ^{\frac{a}{b}}\]
doesnt it change to x^6/3
wow u just said the krop
is that right
|dw:1406228858615:dw|
The denominator becomes: \[\Large \sqrt[3]{x ^{-6}}=x ^{\frac{-6}{3}}\]
so thats the answer right
Not really. At this stage you have: \[\Large\frac{1}{\sqrt[3]{x ^{-6}}}=\frac{1}{x ^{\frac{-6}{3}}}\] You can simplify the denominator further. Can you do that before the final step?
i dont think so and the one get removed and becomes |dw:1406229390064:dw|
What is: \[\Large \frac{-6}{3}=?\]
ohohoho -2
Correct: So now we have: \[\Large \frac{1}{\sqrt[3]{x ^{-6}}}=\frac{1}{x ^{-2}}\] Now multiply numerator and denominator by x^ to get the solution: \[\Large \frac{1}{x ^{-2}}=\frac{1\times x ^{2}}{x ^{-2} \times x ^{2}}=you\ can\ calculate\]
by x^2 *
i have to calculate it now
Remember that:\[\Large x ^{a} \times x ^{-a}=1\]
idk lol
\[\Large \frac{1}{x ^{-2}}=\frac{1\times x ^{2}}{x ^{-2} \times x ^{2}}=x ^{2}\]
