Step by step simplification process to get cube roots radical form and derivative:First we will find all factors under the cube root: 2500 has the cube factor of 125.Let's check this with ∛125*20=∛2500. As you can see the radicals are not in their simplest form.Now extract and take out the cube root ∛125 * ∛20. Cube of ∛125=5 which results into 5∛20All radicals are now simplified. The radicand no longer has any cube factors.

The cubed root of two thousand, five hundred ∛2500 = 13.572088082975

If I'm wrong I'm sorry.

Answer:

Step-by-step explanation:

A perfect cube is a number you get when multiple a number by itself three times.

For example 27 which 3x3x3

Or 126 which 5x5x5

When place 2500 in a calculator and divide it the 3 powered, you don't get a whole number too. so no for 2500

What is the value of y?

Slav-nsk [51]

In a triangle all of the angles always add up to 180, so let's set up an equation.

79 + 37 + y = 180
Simplify
116 + y = 180
Subtract 116 from both sides.
y = 64

The value of y is 64.

Hopefully this helps! If you have any more questions or don't understand, please comment or DM me, and I'll get back to you ASAP. :)

What is an exact solution for <br><img src="https://tex.z-dn.net/?f=m%20%5Csqrt%7B14%7D%20" id="TexFormula1" title="m \sqrt{14}

AlexFokin [52]

Answer: Choice B) $\sqrt{14}$

We have some value m and we're squaring it to get $m^2$

To undo this and isolate m, we apply the square root to both sides

$m^2 = 14\\\\\sqrt{m^2} = \sqrt{14}\\\\|m| = \sqrt{14}\\\\m = \sqrt{14} \text{ or } m = -\sqrt{14}$

There are two solutions here. This is similar to how there are two solutions in something like $x^2 = 25$ (those two solutions being x = 5 and x = -5). Squaring any negative number leads to a positive result because

negative times negative = positive.

Find the equation of a line passing through the point (2, 3) and having a slope of 3.

Delvig [45]

Answer:

The answer to your question is the letter B) y = 3x - 3

Step-by-step explanation:

Data

Point = (2, 3)

slope = m = 3

Process

To solve this problem just substitute the values given in the slope-point equation.

Formula

y - y1 = m(x - x1)

x1 = 2 y1 = 3

-Substitution

y - 3 = 3(x - 2)

-Expand

y - 3 = 3x - 6

-Solve for y

y = 3x - 6 + 3

-Result

y = 3x - 3

Factor:<br><br><br>(m+2)^2−(m+2)+mn·(n+2)+2n(n+2)

bazaltina [42]

ANSWER
${(m + 2)}( {n}^{2} + 2n + m + 1)$

EXPLANATION

The given expression is

${(m + 2)}^{2} - (m + 2) + mn(n + 2) + 2n(n + 2)$

We factor to get,

$= {(m + 2)}(m + 2 - 1) +n (n + 2) (m+ 2)$

This implies that,

$= {(m + 2)}(m + 1) +n (n + 2) (m+ 2)$

We factor further to obtain,

$= {(m + 2)}((m + 1) +n (n + 2))$

or

$= {(m + 2)}( {n}^{2} + 2n + m + 1)$
