Step-by-step explanation:
[tex]( {10.3})^{2} [/tex]
[tex] = (10 + 0.3) ^{2} [/tex]
By using the identity (a+b)^2 = a^2 +2ab +b^2 we get,
[tex] = (10) {}^{2} + 2 \times 10 \times 0.3 + (0.3) {}^{2} [/tex]
[tex] = 100 + 6 + 0.09[/tex]
[tex] = 106.09[/tex]
Hope this helps you out:)
Answer:
(10.3)^2
=(10+0.3)^2
