The concept of radicals and radical exponents is tricky at first, but makes sense when we look into the logic behind it.
When we write a radical in exponential form, like writing √x as x^(1/2), we are simply putting the power of the radical in the denominator (bottom number) of the exponent, and the numerator is the power we raise the exponent to, or the power that would be inside the radical.
In our example, √x is really ²√(x¹), or the square root of x to the first power. For this reason, we write it as x^(1/2).
Let's say we wanted to write the cubed root of x squared, in exponential form.
In radical form, it would look like this:
³√(x²) . This means we square x, and then take the cubed root.
In exponential form, remember that we take the power of the radical (3), and make that the denominator of the exponent, and keep the numerator as the power that x is raised to (2).
Therefore, it would be x^(2/3), or x to the 2 thirds power.
Just like when multiplying by a fraction, you multiply by the numerator and divide by the denominator, in exponential form, you raise your base number to the power of the numerator, and take the root of the denominator.
Answer:
<h2>$58500</h2>
Step-by-step explanation:
let the degree holder earn x
then a masters degree holder earns= (2x-45,000)
the comnined amount of the two degree holders= (2x-45,000)+x
2x-45000+x=117000
3x=117000+45000
3x=162000
x=162000/3
x=$54000
so bachelor'sdegree hold earns= $54000
a masters degree holder earns= (2(54000)-45,000)
a masters degree holder earns= (108000-45,000)
a masters degree holder earns=$63000
the average= (54000+63000)/2
the average= (117000)/2
the average=$58500
Answer:
3(238+12) is the expression
Step-by-step explanation:
hope this helps
Well if each side is 6cm each then u Have to multiply 6x how many sides to the cube there are. So if there are 6 sides to a cube and you have 6cm each side then you have to multiply 6cm X 6 witch = 36 then multiply 36X6=216. So the final answer is 216.
Hope this helps!
