Question

Simplifying radicals with variables and exponents.

Answer 1

\[\huge \sqrt{18n} \times \sqrt{98n^3}\]

Answer 2

tried?

Answer 3

\[\huge \sqrt {18n}=3 \sqrt {2n}\]
\[\huge \sqrt {98}= 7 \sqrt {2}\]
\[\huge \sqrt {n^3}=\sqrt {n} \sqrt{n^2}=n \sqrt {n}\]
\[\huge 3 \times 7 \times n \sqrt{2n \times 2 \times n}\]
\[\huge 21n \sqrt{4n^2}?\]

Answer 4

yes, but that can still be simplified!

Answer 5

\(\sqrt {n^2} = n\)

Answer 6

\(\sqrt 4 = 2\)

Answer 7

\[\huge 21n \sqrt{2n}\]

Answer 8

no...
\(\huge 21n \sqrt{4n^2} = 21n \sqrt 4 \sqrt {n^2} = 21n \times 2n = ...\)

Answer 9

Oh okay
So
\[\huge 42n\]

Answer 10

Oops it didn't show all my work\[\huge 42n^2\]

Answer 11

you are \(\huge \color{red}{\checkmark}\)
