Question

simplify by reducing the radical . 49√y^21z^14

Answer 1

turn the exponents into fractions; a sqrt is just a denominator of 2; reduce as needed

Answer 2

\[\sqrt{y^{21}z^{14}}=y^{21/2}z^{14/2}\]

Answer 3

the answer is \[49y^{10}z^{7}√y\]

Answer 4

well the 49 is supposed to look like \[\sqrt[49]{?}\]

Answer 5

it good to get them into whole numbers as much as possible:

21/2 = 10' 1/2 ; \(y^{10}y^{1/2}\)
14/2 = 7 ; \(x^7\)

Answer 6

lol ..... then 49 is the denominatir :)

Answer 7

49rt(.....) is a good way to ascii it

Answer 8

ooo . so i can have fractions for my exponents?

Answer 9

\[y^{21/49}\ z^{14/49}\]
\[y^{3/7}\ z^{2/7}\]
\[\sqrt[7]{y^3\ z^2}\]

Answer 10

yep; fractional exponents are just a way to write a radical sign

Answer 11

sqrt = ^1/2
cbrt = ^1/3
4rt = ^1/4
.....
n rt = ^1/n
