Answer: 625100
Step-by-step explanation:
To begin, we would start multiply both numbers one by one.
(6.3 x 10^6) - 4.9 x 10^4
6.3 x 10^6 = 6300000
4.9 x 10^4 = 49000
Now, subtract (6.3 x 10^6) and (4.9 x 10^4)
6300000. 49000
6300000 - 49000 = 6251000
Answer:305
Step-by-step explanation:
<span>2√(x-5) = 2
</span><span>√(x-5) = 1
</span>x-5 = 1
x=6(I don't know what extraneous solution means though)

- How do you simplify this?
- x²y+xy² / y²+2/5 × xy


Factor the expressions that are not already factored.

<u>How </u><u>to</u><u> factorise</u><u> </u><u>:</u><u>-</u>
<u>NUMERATOR</u> 

Factor out xy.

<u>DENOMINATOR</u> 

Factor out 1/5.

_____
Continuing...

Cancel out y in both the numerator and denominator.

Expand the expression.

This can further simplified to as 

Well when you convert fractions to decimals, you simply divide the numerator by the dominator.
To convert decimals to percents, you take the fraction and divide the numerator by the dominator and times that by 100.
For example, 4/25*100=16%
