How do you convert a radical expression to a rational exponent and vice versa?

1 answer:

5 0

Take the expression x^2/3 which has an exponent of 2/3. The top of the fraction refers to the power - that is x^2 ( x squared). and the 3 indicates a cubic root.

So in radical form it is ∛(x^2)

Converting radical to exponent an example would be

∛(x^5) = x^(5/3)

If the domain of the function f(x)=2x2- 8is {-2, 3, 5}, then the range is

Simora [160]

Answer:

{0, 10, 42}

Step-by-step explanation:

Domain is set of input values and range is set output values.

For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}

Range is:

f(-2) = 2(-2)² - 8 = 0
f(3) = 2*3² - 8 = 10
f(5) = 2*5² - 8 = 42

Range: {0, 10, 42}

BEEN ASKING FOR A WHILE!! Find the perimeter and area for the triangle. Be sure to write the formula, and use correct measure.

Sauron [17]

Answer:

Area = 77ft²

Perimeter = 44 9/20 feets

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Base = 19 1/4 feets = 77/4 feets

Height = 8 feets

Area = 1/2 * 77/4 * 8

Area = (77 * 8) / 8

Area = 77 feet²

Perimeter of a triangle :

Sum of the sides

Perimeter = a + b + c

Perimeter = 19 1/4 + 10 + 15 1/5

Perimeter = 44 + (1/4 + 1/5)

Perimeter = 44 9/20
