Question

Evaluate 98² using identity.

Answer 1

Answer:

9604

Step-by-step explanation:

98² = (100 - 2)²

      = (100)² - 2 × 100 × 2 + 2²

      = 10000 - 400 + 4

      = 9604

Answer 2

Heya,

_______^_^_______


${98}^{2 } = {{(100 - 2)}}^{2} \\ = {100}^{2} - 2 \times 100 \times 2 + {2}^{2} \\ = 10000 - 400 + 4 \\ = 9604$
