$heya \: \: here \: is \: ur \: answer$

$102 \times 106 = (100 + 2)(100 + 6)$

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

${100}^{2} + (2 + 6)100 + (2 \times 6)$

$10000 + 800 + 12$

$thank \: uh$

Answer 2

heya...

Here is your answer...

102×106

(100+2)(100+6)

(x+a)(x+b) = x^2+(a+b)x+ab

(100)^2+(2+6)100+(2×6)

10000+(8)100+12

10000+800+12

10,812
