Question

[(4⁻¹ - 5⁻¹)⁻¹] ÷ [(5²)³ × 5⁻⁵) it's urgent please, thank you for your time.

Answer 1

Answer Step by step:

[Note - ^ means raised to the power. I can't write it from my desktop]

[(4^ -1 -5^ -1)^ -1] / [(5^2)^3 x 5^ -5)]

=>  [(4x5)^-1 x -1] / [(5^2 x 3) x 5^ -5]

=>  [20^1] / [5^6 x 1/5^5]

=>  20/ [5^6-5]

=>  20/ 5 = 4

Therefore, [(4^ -1 -5^ -1)^ -1] / [(5^2)^3 x 5^ -5)] = 4.

I HOPE THIS HELPS YOU OUT!!
