Question

RESPONDA:

3√20 + √32 - 2√45 + √50

Answer 1

= 3√20 + √32 - 2√45 + √50
= 3√4√5 + √4√8 - 2√9√5 + √25√2
= 3.2√5 + 2√8 - 2.3√5 + 5√2
= 6√5 + 2√8 - 6√5 + 5√2
= 6√5 - 6√5 + 2√8 + 5√2
= 2√8 + 5√2
= 2√2√4 + 5√2
= 2.2√2 + 5√2
= 4√2 + 5√2
= 9√2

Answer 2

3√20+√32−2√45+√50

3√2².5 + √5² - 2√3².5 + √2.5²

3.2√5 + 4√2 - 2.3√5 + 5√2

6√5 + 4√2 - 6√5 + 5√2

9√2
