Sederhanakan logaritma2 berikut!

Jawaban:

a.7

b.4

Penjelasan dengan langkah-langkah:

A.3 log 9 + 3 log 243

3 log 3^2 + 3 log 3^5

=2 3 log 3+5 3 log 3

=2+5=7

B.2 log 240+ 2 log 15

= 2 log (240/15)

= 2 log 16

= 2 log 2^4

= 4 2 log 2

=4

a.) ³log 9 + ³ log 243

³ log 9 × 243

³ log 2187 = 7

b.) ² log 240 – ² log 15

² log 240/15

² log 16 = 4

c.) 4 ^ ⁴log6 + 3 ^ ⁹log 4

* 4 ^ ⁴log 6 = 6

* 3 ^ ⁹ log 4 = 3 ^ 3² log 2² = 3 ^ 2/2 ³log2 = 2

4 ^ ⁴log 6 + 3 ^ ⁹log 4

6 + 2 = 8

d.) 4 ^ ²log 3 + 9 ^ ⅓log 4

* 4 ^ ²log3 = 2² ^ ² log 3 = 2 ^ ²log 3² = 9

* 9 ^ ⅓log 4 = 3²^⅓log4 = 2

4 ^ ²log 3 + 9 ^ ⅓log 4

9 + 2 = 11
