Answer: ![\sqrt{\frac{9}{4} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B9%7D%7B4%7D%20%7D)
Step-by-step explanation:
This is what it is as a mixed number
![\sqrt{2.25}](https://tex.z-dn.net/?f=%5Csqrt%7B2.25%7D)
= ![\sqrt{2\frac{1}{4} }](https://tex.z-dn.net/?f=%5Csqrt%7B2%5Cfrac%7B1%7D%7B4%7D%20%7D)
= ![\sqrt{\frac{9}{4} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B9%7D%7B4%7D%20%7D)
If you want it written in exponential form it would look like this:
![(\frac{9}{4}) ^{\frac{1}{2} }](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B4%7D%29%20%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
Answer:
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
Step-by-step explanation:
![21-x=13 \\ x = 21 - 13 \\ x = 8](https://tex.z-dn.net/?f=21-x%3D13%20%5C%5C%20x%20%3D%2021%20-%2013%20%5C%5C%20x%20%3D%208)
Answer:
8
Step-by-step explanation:
15 x (1/3+1/5) make common denominators and add
15 x (5/15+3/15) add fractions
15/1 x (8/15) 15 and 15 cancel out and become 1
1/1 x 8/1
1 x 8
8
