Question

I) (a+b)² =
ii) (a-b) ² =
iii)a²-b² =
iv) a power m * a power n =
v) a power m/a power n =
vi)(a power m) power n =
vii) a power m/b power m =​

Answer 1

(a+b)2=a2 +2ab+b2

(a-b)2=a2-2ab+b2

a2-b2=(a+b)(a-b)

a power m*a power n=a power m+n

a power m /a power n=a power m-n

Answer 2

Step-by-step explanation:

$1. \: {(a + b)}^{2} = {a}^{2} + 2ab + {b }^{2} \\ 2. \: {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} \\ 3. \: {a}^{2} - {b}^{2} = (a +b )(a -b) \\ 4. \: {a}^{m} \times {a}^{n} = \: {a}^{m + n} \\ 5. \: {a}^{m} \div {a}^{n} = {a}^{m - n} \\ 6. \: {( {a}^{m} )}^{n} = {a}^{m + n} \\ 7. \: {a}^{m} \div {b}^{m} = {(a - b)}^{m}$
