Explain why the cubed root of -8/27 is -2/3

Answers

The cubed root of the fraction -8/27 is -2/3 and is expressed as ((-2)/(3))^3=(-8)/(27).

Given data:

The cube root of a number refers to a value that, when raised to the power of 3, equals the given number. In this case, we are looking at the cube root of -8/27.

When we simplify -8/27, we find that it is a negative fraction. This means that the numerator (8) is negative, while the denominator (27) is positive. When we take the cube root of -8/27, we are essentially finding a value that, when raised to the power of 3, gives us -8/27.

The cube root of -8/27 can be expressed as  ((-2)/(3))^3 , because when we cube -2/3 (raise it to the power of 3), we get -8/27. This is because (-2/3) * (-2/3) * (-2/3) equals -8/27.

Hence, the cube root of -8/27 is indeed -2/3, as ((-2)/(3))^3 equals -8/27. It's important to note that while the fraction itself is negative, the cube root is a negative fraction raised to the power of 3, which yields the original negative fraction.

Answer:

Because the cubed root of the numerator and denominator equals the answer

Step-by-step explanation:

alright, we are trying to understand WHY \sqrt[3]{(-8)/(27) } = -(2)/(3)

You can actually rewrite the first number as -\frac{\sqrt[3]{8} }{\sqrt[3]{27} }

you must look for the number, which three times itself, equals 8...

...and the same thing for the bottom: a number, which three times itself... equals 27.

What number cubed equals 8? The answer is 2

What number cubed equals 27? The answer is 3

...so now we have -2 over 3. You can double check this answer.

-(2)/(3) * -(2)/(3) = (4)/(9)

(4)/(9) * -(2)/(3) = -(8)/(27)

we get the original number that we were looking for the cubed root... SUCCESS.

Find the equation lines
(4, 5)(7, 3)

Answers

Step-by-step explanation:

Hey there!

The equation of a st.line passing through points (4,5) and (7,3) is;

(y - y1) = (y2 - y1)/(x2 - x1) (x - x1)

Putall values.

(y - 5) = (3 - 5)/(7 - 4) (x - 4)

Simplifyit.

(y - 5) = ( - 2)/(3) (x - 4)

3(y - 5) = - 2x + 8

3y - 15 = - 2x + 8

2x + 3y - 23 = 0

Therefore therequiredequationis2x+3y-23=0.

Hope it helps..
