Question

Sin 270 + log² = ?

(³log 36)² - (³log 4)² = ?

³log √12 = ?

log 0,5 = ?

Answer 1

(³log 36 + ³log 4)(³log 36 - ³log 4)
= (³log 144)(³log 9)
= ³log 1296
= ³log 3⁴ x 2⁴
= 4 + ³log 16

³log √12 = ³log √(4 x 3)
= ³log 2 + ³log 3
= 1 + ³log 2

log 0,5 = log 5/10
= log 5 - log 10
= (log 5) - 1
