<span>(4.4*10^6) = 4400000
and
</span><span>(3.9*10^4) = 39000
</span>
The exponents on top of the 10 tells you how many decimals you're supposed to move it to. If it's a negative number, you'll need to move the same amount of decimals, but to the left side instead.
for example: 4.3*10^-3 =0.0043

in this case, however, you should refer to the Laws of Exponents.
<span>(4.4*10^6)*(3.9*10^4)
= 4.4 * 3.9 * 10^6 * 10^4 
= 17.16 * 10^(6+4) <-- Law of Exponents say that when you multiply exponents with the same base, you add the exponents together.
= 17.16 * 10^10</span>

Find the solutions to x2 = 28.
mr Goodwill [35]

Answer: x = \pm2\sqrt{7}\\\\

Work Shown:

x^2 = 28\\\\x = \pm\sqrt{28}\\\\x = \pm\sqrt{4*7}\\\\x = \pm\sqrt{4}*\sqrt{7}\\\\x = \pm2\sqrt{7}\\\\

This can be rewritten into x = 2\sqrt{7} \ \text{ or } \ x = -2\sqrt{7}

If if the branding division were to experience the same percentage increase from year 2 to year 3 as they did from year 1 to yea
Sedaia [141]
Since the basis is from year 1 to year 2, calculate first for the difference of their percentages. That would be:

Difference = year 2 - year 1
Difference = 2.32% - 1.1% = 1.22%

We apply this same value of percentage increase from year 2 to year. Thus, the percentage for year 3 is:

% Year 3 = % Year 2 + percentage increase
% Year 3 = 2.32% + 1.22%
% Year 3 = 3.54%
