8. which is the exponential form of log8 x=3?

C.

Step-by-step explanation:

Given:

Here the base is 8.

We have to convert this log equation to exponential equation.

Let me show you the general form logarithm to exponent.

y = is equivalent to

When we convert log to exponent, the log base become "base" of the exponent y become power  and b become equation as you can see it above.

Therefore, the answer is C.

< 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
