2x³-8=0<br> How do I solve this problem ?
wlad13 [49]

Answer:

x=2^{\frac{2}{3}}

Step-by-step explanation:

1) Add 8 to both sides.

<em />2x^3=8

2) Divide both sides by 2.

x^3=\frac{8}{2}

3) Simplify \frac{8}{2} to 4.

x^3=4

4) Take the cube root of both sides.

x=\sqrt[3]{4}

5) Rewrite 4 as 2².

x=\sqrt[3]{2^2}

6) Use this rule: {({x}^{a})}^{b}={x}^{ab}.

x=2^{\frac{2}{3}}

Decimal Form: 1.587401

__________________________________________

Check the answer:

2x^3-8=0

1) Let x=2^\frac{2}{3}.

2(2^{\frac{2}{3} })-8=0

2) Use this rule: (x^a)^b=x^{ab}.

2\times2^{\frac{2\times3}{3} } -8=0

3) Simplify 2 * 3 to 6.

2\times2^{\frac{6}{3} } - 8  =0

4) Simplify 6/3 to 2.

2\times2^2-8=0

5) Use Product Rule: x^ax^b=x^{a+b}.

2^3-8=0

6) Simplify 2^3 to 8.

8 - 8 = 0

7) Simplify 8 - 8 to 0.

0 = 0

Thank you,

Eddie

The lengths of the sides of triangle ABC are represented in terms of the variable m, where m &gt; 6.
Evgen [1.6K]

Answer: List of the angles from smallest to largest are C, B and A

Step-by-step explanation:

The diagram of triangle ABC is shown in the attached photo. Since none of the sides are equal, then it is a scalene triangle.

From the information given,

AB = m – 2

BC = m + 4

AC = m

It means that the longest side is BC, the medium side is AC and the shortest side is AB. Therefore,

The smallest angle is angle C.

The medium angle is angle B.

The largest angle is angle A
