Answer 1

Answer:

$(5.3)2 - (3.3) \\ 10.6 - 3.3 \\ 7.3 \\ \\ (11.2) - (11.2)(2.4) + (1.2)2 \\ 11.2 - 26.88 + 2.4 \\ - 13.28$

Answer 2

Answer:

1 )

$(5.3)2 - (3.3)$

$10.6 - 3.3$

$= 7.3 \: \: \: ans.$

2)

$(11.2)2 - (11.2)(2.4) + (1.2)2$

${(11.2)}^{2} - (11.2).2.(1.2) + {(1.2)}^{2}$

follow the formula ,

(a - b) ² = a² + b² - 2ab .

$here \: a = 11.2$

$and \: b = 1.2$

therefore,

${(11.2 - 1.2)}^{2}$

$= {(10)}^{2}$

$= 100 \: \: ans \: .$
