Semoga bermanfaat yaa☺☺

A. √8+√18+√32
= √4×2+√9×2×√16×2
= 2√2+3√2+4√2
= 9 √2

B.√98+√50+√72
= √49×2+√25×2+√36×2
= 7√2+5√3+6√2
= 18√2

C.√108+√27+√75
= √36×3+√9×3+√25×3
= 6√3+3√3+5√3
= 14√3

D. √125-√45
= √25×5-√9×5
= 5√5-3√5
= 2√5

E. 2√128-√32+√2+√8
= 2√64×2-√16×2+√2+√4×2
= 2×8√2-4√2+√2+2√2
= 14√2
