Give the Exponential form of the following logarithmic functions. Note: use caret(^) to denote exponents. ie 3 cube is 3^3. Logarithmic Form b Exponential Form
log1/2 16 = -4 Answer = 
Answer
log7 1 = 0 Answer =
Answer
log5 1/sqrt(5) = -1/2  Answer
Answer

< 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
