Answer 1

→ Let

→ E = ⁴√81 - 8(³√216) + 15(⁶√32) + (√225)

→ We shall only consider positive roots of all the terms of the expression E.

→ 81 = (3)⁴, => ⁴√81 = ⁴√(3)⁴ = 3,

→ 216 = (6)³,=> 8(³√216) = 8[³√(6)³] = 8 × 6 = 48,

→ 32 =(2)⁵, => 15(⁵√32) = 15[⁵√32] = 15 × 2 = 30

→ 225 = (15)², => (√225) = [²√(15)²] = 15.

→ E = 3 - 48 + 30 + 15 = 48 - 48 = 0.
