Answer 2

Answer:

$Value \: of \: 6.5\times 6.5 - 45.5 + 3.5 \times 3.5 = 9$

Step-by-step explanation:

$Value \: of \: 6.5\times 6.5 - 45.5 + 3.5 \times 3.5$

$= (6.5)^{2}-2\times 6.5 \times 3.5 + (3.5)^{2}$

$= (6.5 - 3.5 )^{2}$

/* By algebraic identity:

a² - 2ab + b² = (a-b)² */

$= 3^{2}\\=9$

Therefore.,

$Value \: of \: 6.5\times 6.5 - 45.5 + 3.5 \times 3.5 = 9$
