Answer:
No
Step-by-step explanation:
When you square a number, you chose a number and multiplying itself. If you did the square root of 25, you would get 5. However if you divided 25 by 2, you would get 12.5 which is NOT the square root.
#25.
Convert the fractional numbers into decimals for easier comparison.
3 2/3 is approximately 3.66
-4 2/5 is approximately -4.4
We now have: 3, 3.66, -4.2, -4.4
In order: -4 2/5, -4.2, 3, 3 2/3
#26.
All positive numbers are greater than negative numbers.
When comparing two negative numbers, the one with the larger absolute value, will be less.
So (G) is correct
#27.
25 = m + 6.3
25 - 6.3 = m + 6.3 - 6.3
m = 18.7
#28.
h = 3.2-1.6 = 1.6
#29.
x = 15.6 - 9.8 = 5.8
#30
p = 17 - 4.5 = 12.5
Answer:
<h2>12</h2>
Step-by-step explanation:
Hi!
Here is your answer,
I will explain in step by step,
![{x}^{9} = {12}^{2} \times {12}^{7}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B9%7D%20%20%3D%20%20%7B12%7D%5E%7B2%7D%20%20%5Ctimes%20%20%7B12%7D%5E%7B7%7D%20%20)
Here we can simplify this further using this law,
![{a}^{m} \times {a}^{n} = {a}^{m + n}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7Bm%7D%20%20%5Ctimes%20%7Ba%7D%5E%7Bn%7D%20%3D%20%20%7Ba%7D%5E%7Bm%20%2B%20n%7D%20)
So we will get,
![{x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B9%7D%20%20%3D%20%20%7B12%7D%5E%7B7%20%20%2B%202%7D%20%20%5C%5C%20%20%7Bx%7D%5E%7B9%7D%20%3D%20%20%7B12%7D%5E%7B9%7D%20%20)
Since the powers are same we can cancel it out and we will get,
![x = 12](https://tex.z-dn.net/?f=x%20%3D%2012)
(Hope this answer helped :))
