Solve x^5-4x^3 is less than or equal to 0

1 answer:

5 0

Solve for x over the real numbers:
x^3 (x^2 - 4) = 0

Split into two equations:
x^3 = 0 or x^2 - 4 = 0

Take cube roots of both sides:
x = 0 or x^2 - 4 = 0

Add 4 to both sides:
x = 0 or x^2 = 4

Take the square root of both sides:
Answer: x = 0 or x = 2 or x = -2

Simplify by expressing fractional exponents instead of radicals

igomit [66]

Answer:

$a^{\frac{1}{2}}b^{\frac{1}{2}}$

Step-by-step explanation:

Given:

The expression in radical form is given as:

$\sqrt{ab}$

We need to express this in fractional exponent form.

We know that,

$\sqrt a=a^{\frac{1}{2}}$

Also, $\sqrt{ab}=\sqrt a\times \sqrt b$

Now, clubbing both the properties of square root function, we can rewrite the given expression as:

$\sqrt{ab}=\sqrt a \times \sqrt b\\\\\sqrt{ab}=a^{\frac{1}{2}}\times b^{\frac{1}{2}}\\\\\therefore \sqrt{ab}=a^{\frac{1}{2}}b^{\frac{1}{2}}$

So, the given expression in fractional exponents form is $a^{\frac{1}{2}}b^{\frac{1}{2}}$ .

(02.02)A train can travel 744 miles in 3 hours. What is the unit rate that this train is traveling per hour? _____ miles per hou

Fynjy0 [20]

If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.

64 ounces in 8 cups unit rate

Veseljchak [2.6K]

So the unit rate is basically how many ounces in 1 cup?

So since there are 64 ounces in 8 cups, you can just divide by 8, to find how many sets of 8 there are in 64.

64 = 8

64 / 8 = 8 / 8

8 = 1

So there are 8 ounces in 1 cup, which is your unit rate.
