Question

simplify = 4 √81-8 3√216++√225

Answer 1

Step-by-step explanation:

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

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.
