Answer 2

Sure, let's calculate the expressions step by step:

1. 63^4 - 62^4 / (63^2 + 62^2) * 25

Step 1: Calculate 63^4 63^4 = 63 * 63 * 63 * 63 = 63,875,517

Step 2: Calculate 62^4 62^4 = 62 * 62 * 62 * 62 = 57,871,936

Step 3: Calculate (63^2 + 62^2) (63^2 + 62^2) = (63 * 63) + (62 * 62) = 3,969 + 3,844 = 7,813

Step 4: Divide 62^4 by (63^2 + 62^2) 57,871,936 / 7,813 ≈ 7,398

Step 5: Calculate the final expression 63^4 - 7,398 * 25 ≈ 63,875,517 - 184,950 ≈ 63,690,567

So, the value of the first expression is approximately 63,690,567.

2. 86^4 - 74^4 / (32^2 - 8^2) * (86^2 + 74^2)

Step 1: Calculate 86^4 86^4 = 86 * 86 * 86 * 86 = 4,059,027,856

Step 2: Calculate 74^4 74^4 = 74 * 74 * 74 * 74 = 2,609,601,024

Step 3: Calculate (32^2 - 8^2) (32^2 - 8^2) = (32 * 32) - (8 * 8) = 1,024 - 64 = 960

Step 4: Divide 74^4 by (32^2 - 8^2) 2,609,601,024 / 960 ≈ 2,720,834

Step 5: Calculate (86^2 + 74^2) (86^2 + 74^2) = (86 * 86) + (74 * 74) = 7,396 + 5,476 = 12,872

Step 6: Multiply the result from Step 4 by (86^2 + 74^2) 2,720,834 * 12,872 ≈ 35,065,997,648

Step 7: Calculate the final expression 86^4 - 35,065,997,648 ≈ 4,059,027,856 - 35,065,997,648 ≈ -31,006,969,792

So, the value of the second expression is approximately -31,006,969,792.
