i dont no mujhe iska solution nahi pata

Answer 2

Answer:

${x}^{2} {y}^{2} {z}^{2} + {x}^{2} y - {x}^{2} {y}^{2} + 15 \\ = { - 2}^{2} \times {7}^{2} \times { - 2}^{2} + {( - 2)}^{2} \times 7 - {( - 2)}^{2} \times {(7)}^{2} + 15 \\ = 4 \times 49 \times 4 + 4 \times 7 - 4 \times 49 + 15 \\ = 784 + 28 - 196 + 15 \\ = 827 - 196 \\ = 631$
