Answer:

When we have something like:

\sqrt[n]{x}

It is called the n-th root of x.

Where x is called the radicand, and n is called the index.

Then the term:

\sqrt[4]{16}

is called the fourth root of 16.

And in this case, we can see that the index is 4, and the radicand is 16.

At the end, we have the question: what is the 4th root of 16?

this is:

\sqrt[4]{16} = \sqrt[4]{4*4}  = \sqrt[4]{2*2*2*2} = 2

The 4th root of 16 is equal to 2.

Mean of four numbers a ,b, c, and d is 8 and mean of seven
Nana76 [90]

Answer:

  • 17 1/3 or 17.33

Step-by-step explanation:

<u>Mean of four numbers a, b, c, and d is 8:</u>

  • (a + b + c + d)/4 = 8  
  • ⇒ a + b + c + d = 32

<u>Mean of seven numbers x, y, z, a, b, c and d is 12:</u>

  • (x + y + z + a + b + c + d)/7 = 12

<u>Substitute the sum of 4 numbers:</u>

  • x + y + z + 32 = 7*12
  • x + y + z = 84 - 32
  • x + y + z = 52

<u>Mean of x, y and z is:</u>

  • 52/3 = 17 1/3 or 17.33
