Option 3: 2^{\frac{5}{6}} is the right answer

Step-by-step explanation:

Given expression is:

(\sqrt{2})(\sqrt[3]{2} )

In order to simplify the expression we have to convert the radicals in exponents

2^{\frac{1}{2}} . 2^{\frac{1}{3}}

As he base is same, the powers can be added

=2^{\frac{3+2}{6}}\\=2^{\frac{5}{6}}

Hence,

A-One Talent Agency has 108 clients. 42 of the clients play piano and 51 of the clients play guitar.
Butoxors [25]

Thwre are 28 clients who don not play any of the instrument using the principle of Venn distribution.

<u>Using a Venn diagram analogy</u> :

  • Total number of client, U = 108
  • Piano, P = 42
  • Guitar, G = 51
  • Piano and Guitar, (PnG) = 13
  • None =?

<u>From the information given</u> :

  • P only = 42 - 13 = 29
  • G only = 51 - 13 = 38

<u>The total number of clients can be related thus</u> :

  • Total = P only + G only + PnG + None

108 = 29 + 38 + 13 + None

108 = 80 + None

None = 108 - 80

None = 28

Therefore, the number of clients who do not play any of the instruments is 28
