Question

[(4)-¹–(5)-¹]²×(5/8)-¹

mere bhoot likhal gye koi bataa do ​

Answer 1

1/250

OR

250-¹

Step-by-step explanation:

4-¹ = 1/4

5-¹ = 1/5

(5/8)-¹ = 8/5

Now,

[(4)-¹ – (5)-¹]² × (5/8)-¹

= (1/4 – 1/5)²×(8/5)

= (5–4/20)² × 8/5

= (1/20)² × 8/5

= 1/400 × 8/5

by cutting 8 and 1/400 we get 1/50

= 1/50 × 1/5

= 1/250

OR

= (250)-¹
