Answer:

\frac{7\sqrt{5} }{8}

Step-by-step explanation:

Using the rules of radicals

\sqrt{\frac{a}{b} } = \frac{\sqrt{a} }{\sqrt{b} }

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

\sqrt{\frac{245}{64} } = \frac{\sqrt{245} }{\sqrt{64} }

Simplifying the radicals

\sqrt{245}

= \sqrt{5(7)(7)}

= \sqrt{49(5)}

= \sqrt{49} × \sqrt{5} = 7\sqrt{5}

and

\sqrt{64} = 8

The simplified radical is

\frac{7\sqrt{5} }{8}

How can bargain-shopping help spending?
Over [174]

Answer: It is shopping around for the best prices and saves money.

Step-by-step explanation: Bargain has the word "gain" in it. That's the best way I would look at it. Therefor I would cross out any other option that has to do with no benefit or the loss of something. Because we you bargain, you're getting multiple of something for a good price or maybe getting something that's on sale for a good price. For example: Buy 1 get 1 free items.
