Question

√3:(y^10) √3:(81y^11) Multiply and simplify

Answer 1

\[\large\sqrt[3]{y^{10}}\sqrt[3]{81y^{11}}\]

Is this the question?

Answer 2

Yes I am sorry but I do not know how to get those marks on my computer and I am having a really difficult time understanding this even after I am reading my text book :)

Answer 3

\[3\sqrt[3]{3}y^{7}\]

Answer 4

Well, we can re-write this as:
\[(y^{10})^{1/3}(81y^{11})^{1/3}=(y^{10})^{1/3}(81)^{1/3}(y^{11})^{1/3}=(y^{10})^{1/3}3(3^{1/3})(y^{11})^{1/3}\]
Or:
\[\large3\sqrt[3]3 \sqrt[3]{y^{10}}\sqrt[3]{y^{11}}\]
Now, more than likely your book is going to lie and say this can be reduced further... it actually cannot, if x is negative... but they don't like teaching people that...
\[\large 3\sqrt[3]3 * y^7\]

Answer 5

thank u all very much
