Question

Express the following in simplest radical form. All variables represent positive real numbers.
square 9x^9y^4

Answer 1

I know \[\sqrt{9}= \sqrt{3 }\] but what about the 9 and 4

Answer 2

\[\sqrt{9x^9y^4}\]

Answer 3

\(\sqrt{9} \ne \sqrt{3}\)

Answer 4

thats incorrect ok :) i think u mean this :

\(\sqrt{9} = 3\)

Answer 5

That what I meant, so how to get the exponent.

Answer 6

\(\sqrt{9x^9y^4} \)

\(3 \sqrt{x^9y^4} \)

Answer 7

you wanto see if something else can come out of radical

Answer 8

write \(y^4 = (y^2)^2\)

Answer 9

and, write \(x^9 = x^8.x = (x^4)^2.x\)

Answer 10

see if u can simplify further
