Question

Which expression is the simplified form of

Answer 1

\[\sqrt{z^7}\]

Answer 2

what is the exponent of squareroot ?

Answer 3

sqrta =a on what exponent ?

Answer 4

so what is a on exponent 1/2 ?

Answer 5

a^(1/2) = ?

Answer 6

so yes is sqrt(a) =a^(1/2)

Answer 7

\[z^3\sqrt{z}\] i think this is it

Answer 8

there is z^3 sqrt(z) ?

Answer 9

\[z \sqrt{z^3}\]
\[z^2\sqrt{z}\]
\[z^3\sqrt{z}\]
\[z^3\sqrt{z^2}\]
this is the choices

Answer 10

so z^7 =(z^3)^2 *z but sqrt(z^3)^2 =z^3 and from this result that inside radical will remain just z

Answer 11

Im only in 8th grade and you are really confusing me .................

Answer 12

why ? we know that sqrt((z^3)^2) = z^3
yes ?

Answer 13

but inside radical there is z^7 =(z^3)^2 *z
yes ?

Answer 14

so than because sqrt(z^3)^2 =z^3 so than sqrt(z^7) =z^3sqrt(z)

Answer 15

now is clearyfid ?
