Using the formula (a+b)^2=(a^2+2ab+b^2),evaluate: ii》(508)^2 ii》(630)​

Answer 1

Answer:

ok it's the and of 1st part

Answer 2

Step-by-step explanation:

${508}^{2}$

$(500 + 8) ^{2}$

$( {500}^{2} ) + 2 \times 500 \times 8 + (8) ^{2}$

$25000+ 1000 \times 8 + 64$

$25000 + 8000 + 64$

$258064$

hope you got that:)

the next one you try yourself

see I am giving you a hint how to do that.

$2)(600 + 30) ^{2}$

$( {600}^{2} ) + 2 \times 600 \times 30 + ({30}^{2} )$

$3600 + 3600 + 900$

you can add that:)
