Answer:

\frac{8\sqrt{y}}{x}

Step-by-step explanation:

\sqrt{\frac{128x^5y^6}{2x^7y^5}}

we have division inside the square root .

LEts simplify it

128 divide by 2 is 64

use property of exponents to simplify the exponents

\frac{a^m}{a^n} =a^{m-n}

\frac{x^5}{x^7} =x^{5-7}=x^{-2}

\frac{y^6}{y^5} =y^{6-5}=y

\sqrt{\frac{128x^5y^6}{2x^7y^5}}

\sqrt{\frac{64x^{-2}y}{1}}

To make the exponent positive move x to the denominator

\sqrt{\frac{64y}{x^2}}

Now we take square root

square root (64) is 8

square root of x^2 is x

\frac{8\sqrt{y}}{x}

<u>Answer:</u>

\frac{8\sqrt{y} }{x}

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

\sqrt {\frac {128x^5y^6} {2x^7y^5} }

To make it easier to solve, we can also write this expression as:

\sqrt {\frac{128}{2} * \frac {x^5} {x^7} * \frac {y^6} {y^5}}

Now we will cancel out the like terms to get:

\sqrt {64*\frac{1} {x^2}*y }

Taking the square root of the terms to get:

8*\frac {1}{x} .\sqrt{y}

\frac{8\sqrt{y} }{x}

D=rt What does T equal? Lol how is this possible
vampirchik [111]

Answer:

t = D/r

Step-by-step explanation:

you rearrange the equation so that is the subject. when you bring something over the equal sign, it reverses the function so D = r×t becomes t = D/r

Two lines, A and B, are represented by the equations given below: Line A: y = x − 6 Line B: y = 3x + 4 Which of the following sh
nadezda [96]

The solution to the system of linear equations is: (−5, −11).

<h3>What is the Solution to the System of Linear Equations?</h3>

The solution to a system is the x and y -coordinates that satisfies the two linear equations.

Given the linear equations:

Line A: y = x − 6

Line B: y = 3x + 4

Now, equating these two equations

x - 6 = 3x + 4

2x = -10

x = -5

y = -11

Hence, the solution is: (−5, −11), because the point satisfies both equations.

During the 2007 baseball season, Wade was up to bat 10 more times than
bearhunter [10]

Answer:

The number of times Ellis get to bat  is  558.

Step-by-step explanation:

Here, let us assume the number of times Ellis bat = m

So, the number of times Dwight bat =  17 times fewer than Ellis

                                                            = m - 17

Also, number of times Wade got to bat  = 10 more times than Dwight

= ( m- 17 )+ 10

Total number of bat times = 1650

So, the number of times ( Wade + Dwight + Ellis) bat together = 1650

⇒   ( m- 17 )+ 10 + (m - 17) + m =  1650

or, 3 m - 34 + 10 =  1650

or, 3  m = 1674

⇒ m = 1674/3 = 558 , or m = 558

Hence, the number of times Ellis get to bat = m = 558.
