Question

1)38²-28²/47²-19²srohno​

Answer 1

1)

(38²-28²)/(47²-19²) = ( (38-28)(38+28) ) / ( (47-19)(47+19) ) = (10*66)/(28*66) = 5/14

Answer 2

=(38-28)(38+28)/(47-19)(47+19)=10*66/28*66=10/28=5/14

Answer 3

To solve the expression, let's perform the operations step by step:

1. Calculate the squares: 38² = 38 * 38 = 1444 28² = 28 * 28 = 784 47² = 47 * 47 = 2209 19² = 19 * 19 = 361

2. Perform the subtractions inside the parentheses: 1444 - 784 = 660 2209 - 361 = 1848

3. Now, divide the results: 660 / 1848 ≈ 0.35775862069

So, the simplified value of the expression is approximately 0.3578.
