Tolong dong semua soal

Jawaban:

$sqrt{18} + sqrt{50} - sqrt{72}$

$= 3 sqrt{2} + 5 sqrt{2} - 6 sqrt{2}$

$= 2 sqrt{2}$

opsi (a)

$sqrt{12} times sqrt{12}$

$= 12$

opsi(c)

$7 sqrt{6} times 5 sqrt{2}$

$= 35 sqrt{12}$

$= 70 sqrt{3}$

opsi(d)

#no 142 memang langsung dijawab tanpa cara

Penjelasan dengan langkah-langkah:

141.

$sqrt{18} + sqrt{50} - sqrt{72} = 3 sqrt{2} + 5 sqrt{2} - 6 sqrt{2} = 2 sqrt{2}$

142.

$sqrt{12} sqrt{12} = 12$

143.

$7 sqrt{6} times 5 sqrt{2} = 35 sqrt{12} = 70 sqrt{3}$

semoga membantu ☺
