PLEASE HURRY!! simplify completely show all work for full credit

Answer:

$4x^{3}$

Step-by-step explanation:

Given:

$(\frac{192x^{12}}{3x^{3}} )^{\frac{1}{3}}$

Apply exponent rule of distribution:

$\frac{(192x^{12})^{\frac{1}{3}}}{(3x^{3})^{\frac{1}{3}}}$

Simplify the numerator:

$\\\\\frac{4 * 3^{\frac{1}{3}}x^{4}}{(3x^{3})^{\frac{1}{3}}}$

Simplify the denominator:

$\\\frac{4 * 3^{\frac{1}{3}}x^{4}}{3^\frac{1}{3}x}}$

Simplify:

$4x^{3}$

-> To explain this party since it is a bigger jump, $3^{\frac{1}{3}}x$ is on the top and the bottom, so it becomes a one. We are left with a four on the top, and using properties of exponents 4 - 1 = 3, explaining why we have $x^{3}$ leftover too.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

PLEASE HELP!! Dee bought 6 dolls and 2 toy trains for $55. At the same prices, Joy bought 4 dolls and 7 toy trains for $65. What

GuDViN [60]

Answer:

The cost of 1 doll = $ 7.5

and The Cost of 1 toy train = $ 5

Step-by-step explanation:

Let the price of 1 doll = $ x

The price of 1 toy train = $ y

Now, according to the question:

6 x + 2 y = $ 55

and 4 x + 7 y = $ 65

Solving the given system of equation,

From (1), we get

$x= \frac{55 - 2y}{6}$

$4 ({\frac{55 - 2y}{6}} ) + 7y = 65$

or, solving for y , we get

110y - 4y + 21 y = 195

or, 17 y = 85

⇒ y= 85/17 = 5

This implies : 6 x + 2 (5) =55

or, 6x = 55 - 10 = 45

or, x = 45/ 6 = 15/2

Hence, the cost of 1 doll = x = $ 7.5

and the Cost of 1 toy train = y = $ 5
