Solve 2x=54xˆ(2/3)
Please, I need the step by step working to find the value of x
Answers
Answer:
x = 19683 or x = 0
Step-by-step explanation:
Solve for x:
2 x = 54 x^(2/3)
Hint: | Isolate the radical to the left hand side by reversing the equality.
2 x = 54 x^(2/3) is equivalent to 54 x^(2/3) = 2 x:
54 x^(2/3) = 2 x
Hint: | Eliminate the power on the left hand side.
Raise both sides to the power of three:
157464 x^2 = 8 x^3
Hint: | Move everything to the left hand side.
Subtract 8 x^3 from both sides:
157464 x^2 - 8 x^3 = 0
Hint: | Factor the left hand side.
Factor x^2 and constant terms from the left hand side:
-8 x^2 (x - 19683) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by -8:
x^2 (x - 19683) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 19683 = 0 or x^2 = 0
Hint: | Look at the first equation: Solve for x.
Add 19683 to both sides:
x = 19683 or x^2 = 0
Hint: | Look at the second equation: Eliminate the exponent.
Take the square root of both sides:
Answer: x = 19683 or x = 0

How do you solve for the variable?
Answers
Answer:
n=15
Step-by-step explanation:
(subtract 6 from both sides of the equation.)
6+n/5=9
6+n/5-6=9-6
(Now you will have to simplify.)
n/5=3
(You will have to multiply all terms by the same value to eliminate fraction denominators.)
n/5=3
5xn/5=5x3
(You will now have to simplify.)
n=15
And that's how you get your answer.

Carter has a fruit stand. In the morning, he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left. Which solution represents how many bas of peaches, b, Carter will sell before he restocks?
Answers
Answer:
Carter will sell 17 bags of peaches before he restocks.
Step-by-step explanation:
Total pounds of peaches Carter have = [tex]25\frac{1}{2} = \frac{51}{2} = 25.5[/tex]
Weight of each bag = [tex]1\frac{1}{2} = \frac{3}{2} = 1.5[/tex] pound
Number of bag made = [tex]\frac{25.5}{1.5}[/tex] = 17
The number is fully divided , it means no of peaches left = 0 < 3
So,
Carter will sell 17 bags of peaches before he restocks.
The number of bas of peaches, b, Carter will sell before he restocks is 17.
Calculation of the number of peaches:Since he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left.
So here
[tex]= 25.5 \div 1.5[/tex]
= 17

The relationship between the intensity of sound((w)/(m^(2)))and the distance from the source of sound is represented by the equation (i)=((k)/(d^(2))).If you sit only one meter away from the stage at a rock concert the intensity of sound is about 0.1(w)/(m^(2)). If vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)) how close to the stage can she sit?
Answers
Answer:
10 m
Step-by-step explanation:
We are given that the relationship between intensity of sound and distance from the source is given by
Intensity (I)=[tex]\frac{k}{d^2}[/tex]
Where I=Intensity
d=Distance of sound from the source
If distance d=1m
Intensity, I=0.1[tex]w/m^2[/tex]
We have to find how close she can to the stage if vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)).
Using the formula
[tex]0.1=\frac{k}{1}[/tex]
[tex]k=0.1[/tex]
[tex]\frac{0.1}{d^2}\leq 0.001[/tex]
[tex]\frac{0.1}{0.001d^2}\leq 1[/tex]
[tex]\frac{0.1}{0.001}\leq d^2[/tex]
[tex]100\leq d^2[/tex]
[tex]10\leq d[/tex]
[tex]d=10 m[/tex]
Hence, she can sit 10 m away from the stage.

4+2(8²×4²)+6+4+6+6+6+2+2
Answers
Answer:
2084
Step-by-step explanation:
4+2(8²×4²)+6+4+6+6+6+2+2 = 4+2(64*16)+6+4+6+6+6+2+2 = 4 + 2048 + 6 * 5 + 2 = 4 + 2050 + 30 = 2080+4 = 2084
= 4 + 2(64 * 16) + 6 + 4 + 6 + 6 + 6 + 2 + 2
= 4 + 2(1024) + 6 + 4 + 6 + 6 + 6 + 2 + 2
= 4 + 2048 + 6 + 4 + 6 + 6 + 6 + 2 + 2
= 4 + 2048 + 24 + 4 + 4
= 2048 + 12 + 24
= 2048 + 36
= 2084
So, in conclusion, the answer to this question is: 2048.
