4. (ii) (5⁻¹ x 2⁻¹) x 6⁻¹ = (1/5 x 1/2) x 1/6
= 1/10 x 1/6
= 1/60
6. {(1/3)⁻¹ - (1/4)⁻¹} ⁻¹ = {3-4}⁻¹
= (-1)⁻¹
= 1/-1
= -1
7. (i) 25 x t⁻⁴ / 5⁻³ x 10 x t⁻⁸ = 25 x 1/t⁴ / 1/5³ x 10 x 1/t⁸
= 25 x 1 x t⁸ x 5³ / t⁴ x 10
= 25 x 125 x t⁸ / 10 x t⁴
= 3125 x t⁴ / 10
= 312.5 x t⁴
hope it helps you
plz mark me as the brainliest
