Which would be a good estimate for the tax on $97.95 if the tax is 9.5%?
Ahat [919]
It would be $10. There is a formula to this "madness". Divide $97.95 by 9.5%. Ignore the rest of the numbers. (I'm pretty sure it has like 7 or 8, but I only went up to 3. Just make sure you have have the whole number, $10). Hope this helps.

Combine the following expressions:
melisa1 [442]

ANSWER

(4n - 1)\sqrt{3 n} + 3\sqrt{n}

EXPLANATION

The given expression is

\sqrt{48 {n}^{3} }  +  \sqrt{9n}  -  \sqrt{3n}

We remove the perfect squares under the radical sign.

\sqrt{16 {n}^{2}  \times3 n}  +  \sqrt{9n}  -  \sqrt{3n}

We can now take square root of the perfect squares and simplify them further.

\sqrt{16 {n}^{2}}   \times \sqrt{3 n} +   \sqrt{9} \times  \sqrt{n}  -  \sqrt{3n}

This simplifies to:

4n\sqrt{3 n} + 3\sqrt{n}  -  \sqrt{3n}

This further simplifies to:

(4n - 1)\sqrt{3 n} + 3\sqrt{n}
