Which of the following is the radical expression of a^4/9

For this case we must find an expression equivalent to:

By definition of properties of powers and roots we have:

So, rewriting the expression we have:

Option 4

OPTION 4.

Step-by-step explanation:

By definition, Radical expressions are those that use a root.

In this case you have this expression:

 In order to find the radical expression of  , it is important to remember that:

Therefore, once you apply this, you get:

You can observe that it matches with the expression provided in Option 4.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
