Answer:
When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs. When the absolute value of the scale factor is equal to one, neither an expansion nor a compression occurs.
√150=5<span>√<span>6
How?-
</span></span>Since <span>150=25⋅6</span>,
<span><span>√150</span>=<span>√<span>25⋅6</span></span>=<span>√25</span>⋅<span>√6</span>=5<span>√<span>6

Answer:
this is just a guess but 81
Step-by-step explanation:
I hope it is right, but I just did quick math.
so it might also be 82 if you round up to the nearest number. (sorry if this is confusing)
Answer:
560
Step-by-step explanation:
So we know that 20% goes into 100% 5 times.
700/5 will give you a clean 140, meaning 20% of the price is 140
Thus 700-140 and you get 560 dollars
If you have a calc you could also do 700 x .80 (since .80 is also equal to 80%) and get the same answer
The first step to solving this is to remember the radical rules. They state that the product of roots that have the same index are equal to the root of the product. Knowing this,, the expression changes to the following:
![\sqrt{2 x^{3} X 18 x^{5} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%20x%5E%7B3%7D%20X%2018%20x%5E%7B5%7D%20%20%7D%20)
Next you'll add the two exponents together and then calculate the product.
![\sqrt{36 x^{8} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B36%20x%5E%7B8%7D%20%7D%20)
Lastly,, calculate the square root to find your answer.
6
![x^{4}](https://tex.z-dn.net/?f=%20x%5E%7B4%7D%20)
This means that the correct answer to your question will be 6
![x^{4}](https://tex.z-dn.net/?f=%20x%5E%7B4%7D%20)
