a)√20 = √(4*5) = √(2²5) = 2√5
b) √ 72 = √ 2³ x 3² = 6 √ 2
c)
d) ∛(16) = ∛(2⁴) = ∛(2³ × 2) = ∛(2³) × ∛(2) = 2 × ∛(2) = 2∛(2)
g) 4 √80 = ^4√16 * ^4√5 = 2 * ^4√5
f) 4 √240 = ^4√16 * ^4√15 = 2 * ^4√15
b) √ 72 = √ 2³ x 3² = 6 √ 2
c)
d) ∛(16) = ∛(2⁴) = ∛(2³ × 2) = ∛(2³) × ∛(2) = 2 × ∛(2) = 2∛(2)
g) 4 √80 = ^4√16 * ^4√5 = 2 * ^4√5
f) 4 √240 = ^4√16 * ^4√15 = 2 * ^4√15
