Answer 2

Answer:

27 square is 729

16 square is 256

Step-by-step explanation:

Given that

27 square

16 square

To find square of 27 and 16

Solution

As we have to find square of two digit

Let use below method to find square

Let 27 as ab like 2 as a and 7 as b

then take

${a}^{2} \: \: \: \: \: \: 2 \times ab \: \: \: \: \: \: \: \: {b}^{2}$

now

${2}^{2} \: \: \: 2 \times 2 \times 7 \: \: \: {7}^{2}$

by multiplication we get

$4 \: \: \: 28 \: \: \: \:49$

now take last digit of 49 then infront of 9 take last digit of addition of 4 and 28 by addition we get 32 hence take 2 infront of 9 now add with starting digit 4 we get 7 put 7 infront of 2 hence we get

$729$

hence 729 is the square of 27.

Now same for 16

take 1 as a and b as 6 then

${1}^{2} \: \: 2 \times 1 \times 6 \: \: {6}^{2}$

now by multiplication

$1 \: \: \: 12 \: \: \: 36$

take same procedure as taken in above example

we get

$256$

hence 256 is square of 16.
