Answer

Note :- I am answering only 2nd question

(ii) \: (102) {}^{2}  = ?

Solution :-

Using Formula :-

(a + b) {}^{2}  = a {}^{2}  + 2ab + b {}^{2}

Put Value in formula

(100 + 2) {}^{2}

Required Answer :-

(100 + 2) {}^{2}  = (100) {}^{2}  + 2(100)(2) + (2) {}^{2}   \\

(102) {}^{2}  = 10000 + 2 \times 200 + 4 \\ (102) {}^{2}  = 10000 + 400 + 4 \:  \:  \:  \:  \:  \:  \:  \\ (102) {}^{2}  = 10404

(102)² = 10404
