Explain why each non-zero integer has two square roots but only one cube root.
lilavasa [31]

if we have a number like say hmm 4, and we say hmmm √4 is ±2, it simply means, that if we multiply that number twice by itself, we get what's inside the root, we get the 4, so (+2)(+2) = 4, and (-2)(-2) = 4, recall that <u>minus times minus = plus</u>.

so, any when we're referring to even roots like \bf \sqrt[2]{~~},\sqrt[4]{~~},\sqrt[6]{~~}...., the positive number, that can multiply itself an even amount of times, will produce a valid value, BUT the negative number that multiply itself an even amount of times, will also produce a valid value.

now, that's is not true for odd roots like \bf \sqrt[3]{~~},\sqrt[5]{~~},\sqrt[7]{~~}...., because the multiplication of the negative number will not produce a valid value, let's put two examples on that.


\bf \sqrt[3]{27}\implies \sqrt[3]{3^3}\implies 3\qquad because\qquad (3)(3)(3)=27&#10;\\\\\\&#10;however\qquad (-3)(-3)(-3)\ne 27~\hspace{8em}(-3)(-3)(-3)=-27&#10;\\\\[-0.35em]&#10;\rule{34em}{0.25pt}\\\\&#10;\sqrt[3]{-125}\implies \sqrt[3]{-5^3}\implies -5\qquad because\qquad (-5)(-5)(-5)=-125&#10;\\\\\\&#10;however\qquad (5)(5)(5)\ne -125~\hspace{10em}(5)(5)(5)=125


so, when the root is an odd root, you will always get only one number that will produce the radicand.

Answer these 4 for me please help me step by step
tangare [24]

4.

The equation we have is:

\frac{8}{5}a=-6

To solve for "a", we want to isolate it in one side.

For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:

\begin{gathered} 5\cdot\frac{8}{5}a=5\cdot(-6) \\ 8a=-30 \end{gathered}

Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":

\begin{gathered} \frac{8a}{8}=-\frac{30}{8} \\ a=-\frac{15}{4} \end{gathered}

And that is the answer to 4.

What is the exponent for 23,000 when writen in scientific notation​
Fiesta28 [93]

Answer:

2.3 x 10⁴

Step-by-step explanation:

23000 is the number. You need the decimal to be in between the two whole numbers that aren't 0.

2.3 <

2.3 x 10, the exponent after the ten has to move the decimal to the original number of spaces in the original number 23000.

In 23000 its 4 places so your answer would be

2.3 x 10⁴

given the line 2x - 3y - 5 = 0, find the slope of a line that is perpendicular to this line. 3/2 2/3 -3/2
svp [43]
2x-3y-5=0
2x-5=3y
3y=2x-5
y=\frac{2}{3} x- \frac{5}{3}
Gradient of line 1 = \frac{2}{3}
Gradient of line 2;
m_{1} * m_{2} =-1
m_{2} * \frac{2}{3} =-1
m_{2} =- \frac{3}{2}
