Answer 3

To calculate the value of the expression:

(21/22) × (22/23) × (23/24) × (24/25) × (25/26) × (26/27) × (27/28) × (28/29) × (29/30) × (30/31)

You can simplify this by canceling out common terms in the numerators and denominators:

(21/22) × (22/23) × (23/24) × (24/25) × (25/26) × (26/27) × (27/28) × (28/29) × (29/30) × (30/31)

= (21/22) × (1/23) × (1/24) × (1/25) × (1/26) × (1/27) × (1/28) × (1/29) × (1/30) × (1/31)

Now, multiply all these fractions together:

(21/22) × (1/23) × (1/24) × (1/25) × (1/26) × (1/27) × (1/28) × (1/29) × (1/30) × (1/31) ≈ 5.0120284292e-18

So, the approximate value of the expression is approximately 5.0120284292e-18.
