Question

3sqrt{y^13} 3sqrt{81y^14} 3sqrt{y^13} 3sqrt{81y^14} @Mathematics

Answer 1

\[3\sqrt{y ^{13}} 3\sqrt{81y ^{14}}\]

Answer 2

\[81\sqrt{y^{27}}\]

Answer 3

\[3y ^{9}*\sqrt[3]{3}\]

Answer 4

im not getting those. how did you get the answer

Answer 5

\[3\sqrt{y^{13}3\sqrt{81y^{14}}}\]

Answer 6

Which is the correct question?

Answer 7

\[\sqrt[3]{y^{13}\sqrt[3]{81}}\]

Answer 8

the one that i typed in as the equation at the very top

Answer 9

i have to multiply the two

Answer 10

\[\sqrt[3]{y ^{13}}*\sqrt[3]{81y ^{14}}\]
\[y ^{13/3}*y ^{14/3}*81^{1/3}\]
\[y ^{27/3}*\sqrt[3]{27}*\sqrt[3]{3}\]
\[y ^{9}*3*\sqrt[3]{3}\]

Answer 11

\[y ^{9}*3^{4/3}\]

Answer 12

\[81 y^{27/2} \]Replace y by 0.7 in the following list and evaluate each list element:\[\left\{81 \sqrt{y^{13}} \sqrt{y^{14}},81 y^{27/2}\right\}\text{ /. } y\to 0.7 \]\[\{0.656612,0.656612\} \]

Answer 13

Y is a variable, it can have any value

Answer 14

Not a complete "proof", but I claim that the second list element is a valid simplification of the problem expression.
