( 8√6 : 2√2 ) * √3 ||| Angka 8 nya dipindain ke akarnya jadi 64, sama juga angka 2 dipindain ke akarnya jadi 4.

1. (√81 : √9) * √16 = (√ 81 : 9 ) * √16

= √9 * √16 = √(9 * 16)

= √144

= 12

 

2. ( 8√6 : 2√2 ) * √3 ||| Angka 8 nya dipindain ke akarnya jadi 64, sama juga angka 2 dipindain ke akarnya jadi 4.

= (√6 * 64 : √2 * 4) * √3

= (√384 : √8) * √3

= √48 * √3

= √144 ||| Ini memang hasil 48 * 3 ya bukan langsung ambil dari nomor 1 tadi

= 12

 

3. (2√3 * √18) : √2

= (√3 * 4 * √18) : √2

= (√12 * √18) : √2

= √216 : √2

= √108

= √2 * 2 * 3 * 3 * 3

= 2 * 3 √3

= 6√3

 

 

4. (√343 * √175) : √1225

= √60025 : √1225

= √49

= 7

 

Catatan: Selama bilangan ada di dalam akar, lalu dikalikan sesama bilangan akar, itu bisa dihitung (√2 * √2 = √4), tapi belum diakarkan (maksudnya √4 = 2).

Babies get sick more often than older children or adults because their immune systems are not fully developed and functioning at full capacity , The common cold , which is an infection of the respiratory system caused by a virus , is the most frequent malady . Doctors say that normal , healthy babies get up to about seven colds before they reach their first birthday . Another common affliction is the flu , caused by a different family of viruses , which bring on high fever , chills , fatigue , and sometimes digestive symptoms like vomiting and diarrhea , in addition to the respiratory symptoms of a cold . Another reason babies get sick so often is that they are frequently around other children , often siblings , and this exposes them to viruses and bacteria at school and daycare . Children at schools and daycare get more colds , runny noses , and earinfections than children cared for at home . However , their earlier exposure to these diseases also leads them to develop immunity earlier
