The answer is 100x2 because 20x5= 100 and the power of 2 is alone, so that’s the answer.

√20x *√5x3 - We can involve the action under the square root, because we have a multiplication of two square root elements.

\sqrt{20x*5x^{3}}  =  \sqrt{20*5 x^{4} } =  \sqrt{100} *x^{2} = 10x^{2}

We are using the fact, that the multiplication of the square roots is alternating.

when n basketball uniforms are purchased , the cost , C , of each uniforms is given by the equation C=40n+260/n. if the cost of
Luda [366]

Hello!

As you can see, C is the cost of each uniform. This would give us the equation below, if each uniform was $60.

60=40n+260/n

Let's multiply both sides by n.

60n=40n+260

Now, let's subtract 40n from both sides.

20n=260

We divide both sides by 20.

n=13

Therefore, 13 uniforms were purchased.

I hope this helps!

Please help!! (please don’t reply if you’re just going to say “ don’t know “ etc please and thank you)
Nastasia [14]

Answer:

a = -1 , b = 4 , c = 3 , d = 1

Step-by-step explanation:

The general rules of exponent:

1) \ a^m * a^n = a^{m+n}\\2) \ a^m / a^n = a^{m-n}\\3) (-1)^m = 1 \ (if \ m \ is \ +) and \ = \ -1 \ (if \ m \ is \ -)

===================================================

Given:

(-xy)^3 (xz) =ax^by^cz^d

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z

Comparing the right hand side with the left hand side

∴ a = -1

∴ b = 4

∴ c = 3

∴ d = 1
