Answer:
![x =2 0](https://tex.z-dn.net/?f=x%20%3D2%200)
Step-by-step explanation:
![{81}^{5} = {3}^{x}](https://tex.z-dn.net/?f=%20%7B81%7D%5E%7B5%7D%20%20%3D%20%20%7B3%7D%5E%7Bx%7D%20)
We know that 3^4 = 81. So :
![= > { ({3}^{4}) }^{5} = {3}^{x}](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20%7B%20%28%7B3%7D%5E%7B4%7D%29%20%7D%5E%7B5%7D%20%20%3D%20%20%7B3%7D%5E%7Bx%7D%20)
![= > {3}^{4 \times 5} = {3}^{x}](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20%7B3%7D%5E%7B4%20%5Ctimes%205%7D%20%20%3D%20%20%7B3%7D%5E%7Bx%7D%20)
![= > {3}^{20} = {3}^{x}](https://tex.z-dn.net/?f=%20%20%3D%20%20%3E%20%20%7B3%7D%5E%7B20%7D%20%20%3D%20%20%7B3%7D%5E%7Bx%7D%20)
Here both the Right hand side & Left hand side has same base i.e. have 3 as base in both the sides.
So , eliminating the base gives :-
![x = 20](https://tex.z-dn.net/?f=x%20%3D%2020)
1 meter = 100 cm
2 meters = 200 cm
200 cm - 54 cm = 146 cm
Your answer is 146 cm or 1.46 m
Answer:
x = 8
Step-by-step explanation:
I am assuming that you mean
22
![\frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20)
, which is 22.25
and
11
![\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20)
, which is 33.75
so each share gives you a profit of 33.75-22.25=11.5
and you bought and sold 25 of them, so your profit is 21.5*25=287.50, the last answer!
