Question

find the value of u³ + v³ and uv if u + v=5 and u - v = 3​

Answer 1

Answer:

u - v = 3 goes with 247

u + v = 5 goes with 255

Step-by-step explanation:

1. u³ = 125

2. v³ = 125

3. 125 + 125 = 250 + 5 = 255

4. u³ = 125

5. v³ = 125

6. 125 + 125 = 250 - 3 = 247

7. u - v = 3 goes with 247

8. u + v = 5 goes with 255
