Answer» Simplify it :- 1) 12² - 5² Given to find the simplification of 12² - 5². To do so, FOLLOW the steps; When, bases are not same and exponents are same, we MUST subtract the bases only, as follows. 12² - 5² (12 - 5)² → 7². Hence, 7² = 7 × 7 = 49. $\\$ 2) 52² - 9² Given to find the simplification of 52² - 9². To do so, follow the steps; When, bases are not same and exponents are same, we must subtract the bases only, as follows. 52² - 9² (52 - 9)² → 43² Hence, 43² = 43 × 43 = 1849. $\\$ More Information :- When, bases are not same and exponents are same, we must subtract the bases only. Ex. aᵐ - bᵐ

Given to find the simplification of 12² - 5². To do so, FOLLOW the steps;

When, bases are not same and exponents are same, we MUST subtract the bases only, as follows.

12² - 5²

(12 - 5)²

→ 7².

Hence, 7² = 7 × 7 = 49.

Given to find the simplification of 52² - 9². To do so, follow the steps;

When, bases are not same and exponents are same, we must subtract the bases only, as follows.

52² - 9²

(52 - 9)²

→ 43²

Hence, 43² = 43 × 43 = 1849.
