We are given the following expression:

$\sqrt[3]{875}$

We can factor 875 as:

$\sqrt[3]{125\times7}$

Now we will use the following property:

$\sqrt[x]{a\times b}=\sqrt[x]{a}\times\sqrt[x]{b}$

Applying the property:

$\sqrt[3]{125}\times\sqrt[3]{7}$

Solving the cubic root on the left:

$5\sqrt[3]{7}$

Since we get simplify any further this is the answer.

How many 1/3 inch cubes does it take to fill a box with width 2 213 inches, length 3 1/3

MAVERICK [17]

Answer:

560 cubes

Step-by-step explanation:

Is 2 213 supposed to read 2 1/3? First calculate the volume of the box

V_box = 8/3 * 10/3 * 7/3 = 560/27 cubic inches

Now calculate the volume of your 1/3 inch cube:

V_cube = 1/3 * 1/3 * 1/3 = 1/27 cubic inches

Now divide the V_box by V_cube:

Number of boxes = (560/27) / (1/27) = (560/27) * (27/1) = 560 cubes

F(x)=25x^2-10x+1 what is the the value of the discriminant of f

Elanso [62]

Answer:

Step-by-step explanation:

Quadratic equation

$x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}$

The discriminant is the part of the quadratic formula within the square root symbol: ${b^{2}-4*a*c}$ . The discriminant indicates if there are two solutions, one solution, or none.

The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.

So, a positive discriminant tell us that the quadratic has two different real solutions.

A discriminant of zero tell us that the quadratic has two real and equal solutions.

And a negative discriminant tell us that none of the solutions are real numbers.

In this case: 25x^2-10x+1=0

We can see that

a= 25 b=-10 c=1

Using: ${b^{2}-4*a*c}$

We have $-10^{2}-4* 25*1 =100-100=0$

the answer is zero, so the quadratic has two real and equal solutions

Rewrite the expression using only positive integer exponents.

Andrews [41]

Answer:

So we got:

$\left(m^{\frac{2}{3}}n^{\frac{-1}{3}}\right)^6$

$m^4\left(n^{\frac{-1}{3}}\right)^6\\$

More attention for $(n^{\frac{-1}{3}}\right))^6\\$

$n^{-2}$

$\frac{1}{n^2}$

Join:

$m^4\frac{1}{n^2}$

$\frac{1\cdot \:m^4}{n^2}\\\frac{m^4}{n^2}$

Therefore, the answer is $\frac{m^4}{n^2}$ , letter A

Which expression is equivalent to 8/9 divided by 3/4

ipn [44]

Step-by-step explanation:

Dividing by a fraction is the same as multiplying with the opposite of the fraction. 8/9 / 3/4=8/9×4/3=32/27=1 5/27.
