Question

4) Using the given clues and identities find the value. ​

Answer 1

Answer:

103² = (100+3)²

= 100²+3²+2(100)(3)

= 10000+9+600

=10,609

97²= (100-3)²

= 100²-2(100)3 + 3²

= 10000-600+9

= 9409

101²= (100+1)²

= 100²+1²+2(100)1

= 10000+1+200

=10,201

I hope this helps you

$1. \: (103 {)}^{2} \\ (100 + 3 {)}^{2} \\ 10 {0}^{2} + 2(100)(3) + {3}^{2} \\ 10000 + 600 + 9 \\ 10609$

$2. \: (97 {)}^{2} \\ (100 - 3 {)}^{2} \\ 10 {0}^{2} - 2(100)(3) + {3}^{2} \\ 10000 - 600 + 9 \\ 9409$

$3. \: (101 {)}^{2} \\ (100 + 1 {)}^{2} \\ 10 {0}^{2} + 2(100)(1) + {1}^{2} \\ 10000 + 200 + 1 \\ 10201$
