tentukan nilai tolong jawab yg di gambar no 1 sampai 3 saja

1 sampai 3 berarti a sampai c ya...

JAWAB

a. 2log(1/8) + 3log3-² + 5log5-³
= 2log8-¹ + (-2)3log3 + (-3)5log5
= 2log2-³ + (-2).1 + (-3).1
= (-3).1 - 2 - 3
= -3 - 5
= -8

b. 8log4 + 27. log¼
= 2³log2² + 3³.log2-¹
= ⅔(2log2) + 27. (-1)log2
= ⅔ - 27.log2

c. √2log 8 = (2^½)(log2³) = (3/½).2log2 = 6.1 = 6

d. √3log9 = (3^½)(log3²) = (2/½).3log3 = 4.1 = 4
