Answer 2

\[a. 7x ^{3}y ^{8}\]\[b. 7x ^{3}\left| y ^{8} \right|\]
I think it is one of these two

Answer 3

Answer 4

My work ? Is that what you are asking ?

Answer 5

yeah! is \[7x ^{3}y\]

Answer 6

sorry \[y ^{8}\]

Answer 7

So the first one ?

Answer 8

@angelwings996

Yes show me the working.

Answer 9

Okay, bt I am not sure if I did it right bcz I came up with 7xy^8 so I guessed that it was either a or b

Answer 10

@angelwings996 Show me your working first.

Answer 11

\[\sqrt[3]{7^{3} x ^{3*3} y ^{8*3}}\]\[\sqrt[3]{7^{3} (x ^{3)^{3}} (y ^{8})^{3}}\]\[\sqrt[3]{(7xy ^{8})^{3}}\]\[7xy ^{8}\]

Answer 12

@hba This is my work

Answer 13

Okay good :)

Answer 14

How did I get x instead of x^3 ?

Answer 15

Because you did it wrong.

Answer 16

what did i do wrong ?

Answer 17

\[\huge\ \sqrt[3]{343x^{9}y^{24}}\]

\[\huge\ \sqrt[3]{7^3x^{9}y^{24}}\]

Answer 18

\[\huge\ ({7^3x^{9}y^{24}}) ^{1/3}\]

Now please work

Answer 19

Oh...then it becomes \[7x ^{3}y ^{8}\]
