How does finding the square root of a number compare to finding the cube root of a number? Use the number 64 in your explanation
dimulka [17.4K]

Answer:

To find the cube root of a number is a bit more complicated and in our days is considered impractical, but here is a method explained. Look at the 2nd example scrolling down about 1/3 of the page

If you want to know the concept of square roots and cube roots ?

the square root of a number is that number which when multiplied by itself two times gives us that number

e.g.

√64 = x , so that (x)(x) = 64

and from our multiplication table we know that

(8)(8) = 64 , so that

√64 = 8

the cube root of a number is that number which when multiplied by itself three times gives us that number

e.g.

∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64

so ∛64 = 4

A half of a class and a half of a student got A on a test. If yet another student got an A, then two-thirds of the class would h
svlad2 [7]

Answer:

6 students.

Step-by-step explanation:

let the number of students in class be<em> x</em>

Since Half of the class represents half of the students, therefore

Number of student who got A in test = \frac{x}{2}

Now if one more student got A in test then the number of students who got A in test will be \frac{x}{2} +1

Now according to equation,

\frac{2x}{3} = \frac{x}{2} +1

\frac{2x}{3} - \frac{x}{2} = 1

Further solving

\frac{4x-3x}{6} = 1

x = 6

Hence the total number of students in class is 6.
