Penjelasan dengan langkah-langkah:

$sfsqrt{frac{625}{5}} + 2sqrt{5}$

$sf=sqrt{125} + 2sqrt{5}$

$sf=sqrt{{5}^{2} times 5} + 2sqrt{5}$

$sf=sqrt{{5}^{2}}sqrt{5}+ 2sqrt{5}$

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

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

$sf=7sqrt{5}$

$sqrt{ frac{625}{5} } + 2 sqrt{5} \ \ = sqrt{125} + 2 sqrt{5} \ \ = sqrt{25 times 5} + 2 sqrt{5} \ \ = 5 sqrt{5} + 2 sqrt{5} \ \ = (5 + 2) sqrt{5} \ \ = 7 sqrt{5}$
