Answer

Options B and C are correct.

(5⁸/5⁴) = 625

(5²)² = 625

Step-by-step explanation

We need to first know that

625 = 5⁴

So, the options that the laws of indices allow us to reduce to 5⁴

Option A

(5⁻²/5²) = 5⁻²⁻² = 5⁻⁴ = (1/5⁴) = (1/625)

This option is not correct.

Option B

(5⁸/5⁴) = 5⁸⁻⁴ = 5⁴ = 625

This option is correct.

Option C

(5²)² = 5⁴ = 625

This option is correct.

Option D

(5⁴) (5⁻²) = 5⁴⁻² = 5² = 25

This option is not correct.

Hope this Helps!!!
