Question

Find the value of (10.3) raised to the whole square 2 using identities

Answer 1

Answer:

here is your answer

Explanation:

(10.3)^2

=(10)^2+(0.3)^2+2(10)(0.3)

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

=100+0.09+6

=106.09

Therefore,

(10.3)^2=106.09

Answer 2

Answer:

106.09

Explanation:

solution:- (10+0.3)^2

using identie, (a+b)^2=a^2+b^2+2(10)(0.3)

(10+0.3)=(10)^2+(0.3)^2+2(10)(0.3)

=100+0.09+6

=106.09

Therefor,

(10.3)^2=106.09
