Hi friend!
Q: Evaluate: 7.6² - 2.4²
Either from Chp. 9 or 13 from Math. Class VIII NCERT
Whatever, we need to use identities and evaluate here.
Answer:
7.6² - 2.4² resembles a² - b².
a² - b² = (a + b)(a - b)
7.6² - 2.4² = (7.6 + 2.4)(7.6 - 2.4)
= (10)(5.2)
= 52
Therefore, 7.6² - 2.4² = 52.
Hope you found my answer helpful. Keep Smiling!
