Don't understand why you have / and then ÷
also I will assume you meant 0.7561×(35.2)^3/(0.25)÷(0.03)^3
Before you take the 4th root you should have: 4,885,437,432
now take 4th rooot of that
4th root of 0.7561×(35.2)3/(0.25)÷(0.03)3

The use of two different signs for division makes me think it's
(0.7561×(35.2)^3) / ((0.25)÷(0.03)^3) = 3.56148
so ∜[(0.7561×(35.2)^3)/((0.25)÷(0.03)^3)] = 1.37375
(0.7561×(35.2)^3) / ((0.25)÷(0.03)^3) = 3.56148
so ∜[(0.7561×(35.2)^3)/((0.25)÷(0.03)^3)] = 1.37375
