George and veronica are both musicians who sell their sogn online during the same year George sold 8x10^5 download of his song a

anygoal [31]

George sold:

$\begin{gathered} 8\times10^5 \\ =800,000 \end{gathered}$

and Veronica sold:

$\begin{gathered} 4\times10^6 \\ =4,000,000 \end{gathered}$

As expanding the scientific notation numbers, we see that

George sold eight hundred thousand

Veronica sold 4 million

How many time is 4 million of 8 hundred thousand?

We simply divide!

$\frac{4,000,000}{800,000}=5$

So,

Veronica's song was downloaded 5 times the numebr of that of George.

B is the right answer.

Simplify the following expression completely, where x is greater than or equal too 0.

Dennis_Churaev [7]

First you want the numbers under the radical to be the same so you can combine like terms.

$x \sqrt{5xy^4} =x \sqrt{5x*^4y} = xy^2 \sqrt{5x}$
$\sqrt{405x^3y^4} = \sqrt{5x*81x^2y^4} =9xy^2 \sqrt{5x}$
$\sqrt{80x^3y^4} = \sqrt{5x*16x^2y^4} = 4xy^2 \sqrt{5x}$

Now add together to get $14xy^2 \sqrt{5x}$
