First we have to just multiply it.
6.2*105=651
Scientific notation require that first part is between 0 and 9 and second its 10 to the power of something. Lets focus on the first part at the begging. We can divide 651 by 100 to get 6.51, so its between 0 and 9 ===> ok. Now we have note down dividing by 100 by 10 to the power of something. As we know that when we put minus to the exponent we obtain inverse number. Finally we can write 100=10^2
Now we put minus in front of 2 to get dividing by 100.
Final form is 6.2*105=651=6.51*10^(-2)
Hope that helps

Can someone explain this to me.

Answer:

option D

3*(\sqrt{x}+\sqrt{x-3})

Step-by-step explanation:

Given in the question an expression,

\frac{9}{\sqrt{x} -\sqrt{x-3}}

Step 1

Divide and multiple by \sqrt{x}+\sqrt{x-3} to remove radical sign from denominator.

\frac{9}{\sqrt{x} -\sqrt{x-3}}*\frac{\sqrt{x} +\sqrt{x-3}}{\sqrt{x} +\sqrt{x-3}}

Step 2

Apply a² - b² = (a+b)(a-b)

\frac{9*\sqrt{x}+\sqrt{x-3}}{\sqrt{x^{2}}-\sqrt{(x-3)^{2}}}}

Step 3

\frac{9*\sqrt{x}+\sqrt{x-3}}{x-x+3}

Step 4

\frac{9*\sqrt{x}+\sqrt{x-3}}{3}

Step 5

3*(\sqrt{x}+\sqrt{x-3})

11/8 miles   divided by 1/4 hr

11/8 ÷ 1/4

11/8 * 4/1 =44/8 = 5 4/8 miles in 1 hr or 5 1/2 miles per 1 hr
