Question

Tolong 3 dan 4. a-d dijawab?

Answer 1

3a. 10log20 = 10log(2.10)=10log2+10log10=0,3010+1=1,3010

b. 10log(2.10²)=0log2+10log10²= 0,3010+2=2,3010

c. 10log(2.10³)=10log2+10log10³= 0,3010+3=3,3010

d. 10log(2.10⁴)=10log2+10log10⁴= 0,3010+4=4,3010

4a. 10log2+10log2= 0,3010+0,3010=0,6020

b. 10log2+10log3 = 0,3010+0,4771=0,7781

c. 10log3+10log3 = 0,4771+0,4771=0,9542

d. 10log2²+10log3 = 2(0,3010)+0,4771=0,6020+0,4771=1,0791
