112: Operations with Radicals - Divide - Marjorie Brewer | Library

Bell Assignment:

Simplify each:
(review: \sqrt{-1}=??)

1

-2\sqrt{100}+2\sqrt{-36}+5\sqrt{-49}

1

2\sqrt[3]{216}-4\sqrt[3]{-512}-5\sqrt{-1}-\sqrt{-100}

Notes L6-5b: Dividing Radicals
If numerator and denominator have the same type of radical:
divide
simplify radical
example: \frac{\sqrt{80x^{4}}}{\sqrt{5x^{3}}}

1

\frac{\sqrt{28x^6}}{\sqrt{7}}

1

\frac{\sqrt{784x^{11}y^{11}}}{\sqrt{7x^{4}y^{2}}}

1

\frac{\sqrt{35x^4}}{\sqrt{7x^4}}

If there is only a square root in the denominator:
rationalize
example: \frac{1}{\sqrt{12}}

1

\frac{3}{\sqrt{28}}

1

\frac{6}{\sqrt{3}}

1

\frac{4y^3}{\sqrt{20y^2}}

1

\frac{n}{\sqrt{4n^7}}
