Question

1. 2log2048=
2. 3log9+9log81=
3. 2log125=
4. 3 3log10+3log9=
5. 4log64

Answer 1

1) ²log 2048 
= ²log 2¹¹
= 11

2) ³log 9 + ⁹log 81
= ³log 3² + ⁹log 9²
= 2 + 2 = 4 

3) ²log 125
= ²log (25 x 5)
= ²log 25 + ²log 5

4) 3 ³log 10 + ³log 9
= 3 ³log 10 + 2

5) ⁴log 64
= ⁴log 4³
= 3

Maaf kalau salah
