Sederhanakanlah bentuk akar berikut

a. 5 ( √2 + 2√6 ) =
b. √18 ( 3 – 5 √2 ) =

tolong dijawab makasihh

Sederhanakanlah bentuk akar berikut

$sf5( sqrt{2} + 2 sqrt{6} ) =$

$sf = 5 sqrt{2} +( 5 times 2) sqrt{6}$

$sf = 5 sqrt{2} +10 sqrt{6}$

— – — – — – — – — – — – — – —

$sf sqrt{18} (3 - 5 sqrt{2} ) =$

$sf = red{sqrt{ 3^{2} times 2}} (3 - 5 sqrt{2} )$

$sf = red{sqrt{ 3^{2}} sqrt{2} } (3 - 5 sqrt{2} )$

$sf = 3 sqrt{2} (3 - 5 sqrt{2} )$

$sf = 3 sqrt{2} times 3 - 3 sqrt{2} times 5 sqrt{2}$

$sf = 9 sqrt{2} - 30$
