WILL GIVE BRAINLIEST HELP!!
Lera25 [3.4K]
Answer is : \sqrt[4]{5}

Explanation: 
\frac{ \sqrt[4]{400}}{ \sqrt[4]{5}} = \frac{ \sqrt[4]{4*5*5*2*2} }{\sqrt[4]{5}}

= \frac{\sqrt[4]{5*5*2*2*4}}{\sqrt[4]{5}} =  \sqrt[4]{5*2*2*4}

= \sqrt[4]{5*2*2*4} =  \sqrt[4]{80} 
= \sqrt[4]{2*2*2*2*5}
= \sqrt[4]{2^{4}} \sqrt[4]{5}
= \sqrt[4]{5}

What’s 8/15 divided by 4/5
iragen [17]

Answer: 2/3

Step-by-step explanation: In this problem, we have 8/15 ÷ 4/5. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction.

8/15 ÷ 4/5 can be rewritten as 8/15 × 5/4

Now, we are simply multiplying fractions so we multiply across the numerators and multiply across the denominators.

8/15 × 5/4 = 40/60 = 2/3

On a coordinate plane, quadrilateral J K L M with diagonals is shown. Point J is at (4, 5), point K is at (5, 1), point L is at
Nata [24]

Answer:

LM = MJ = 3

JK = KL = \sqrt{17

Step-by-step explanation:

Given

J  = (4,5)

K = (5,1)

L = (1,2)

M = (1,5)

Required

Prove it's a kite

Start by calculating the length of the sides of the kite using:

d = \sqrt{(x_1 - x_2)^2 + (y_1 -y_2)^2}

JK = \sqrt{(4 - 5)^2 + (5 -1)^2} = \sqrt{17}

KL = \sqrt{(5 - 1)^2 + (1 -2)^2} = \sqrt{17}

LM = \sqrt{(1 - 1)^2 + (2 -5)^2} = \sqrt{9} =3

MJ = \sqrt{(1 - 4)^2 + (5 -5)^2} =\sqrt{9} = 3

Hence:

LM = MJ = 3

JK = KL = \sqrt{17

proves that it is a kite
