Answer:

256x^8 y^20

that's the answer I got when I simplified it

Answer:

=256x^8y^{20}

Step-by-step explanation:

We have the expression:

(4x^2y^5)^4

We can use the power of a product property:

(ab)^x=a^xb^x

This yields:

=(4)^4\cdot(x^2)^4\cdot(y^5)^4

We can evaluate 4 to the fourth:

=256(x^2)^4\cdot(y^5)^4

Now, we can use the power of a power property:

(x^a)^b=x^{ab}

So:

=256(x^{2(4)})(y^{5(4)})

Multiply:

=256x^8y^{20}

And we're done!

One number is 8 greater than another. The product of the numbers is 84. Find the numbers.
mario62 [17]

Let x,y be the two numbers.

Given that one number is 8 greater than another.

Let x be the smaller number ans y be the greater number.

That is y=x+8. Let this be the first equation.

And also given that product of the two numbers is 84.

That is x × y = 84, let us plugin y=x+8 here.

x × (x+8) = 84

x²+ 8x -84 = 0.

x²+12x-4x-84 = 0

x(x+12)-4(x+12) =0

(x-4)(x+12)=0

That is x= 4 or -12.

<h3>If x=4 , y= 4+ 8 = 12</h3>

<h3>If x= -12, y= -12+8 = -4 </h3>

Hence two positive numbers corresponding to given conditions are 4,12.

And two negative numbers corresponding to given conditions are -12,-4.

Step-by-step explanation:

hope it may help you!!

Triangle A B C is cut by line segment S T. Line segment S T goes from side A B to side C B. Lines S T and A C are parallel. The
maksim [4K]

Answer:

Option C.

Step-by-step explanation:

Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.

Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.

Using triangle proportionality theorem we get

\dfrac{SA}{SB}=\dfrac{CT}{BT}

\dfrac{SA}{10}=\dfrac{2.7}{9}

On cross multiplication we get

9\times SA=2.7\times 10

9SA=27

Divide both sides by 9.

SA=3

The length of SA is 3ft.

Therefore, the correct option is C.
