Given :The given expression is $1234567 \times 23456$.To do :We have to find the value of the given expression.Solution :While multiplying very big numbers it helps if we break down into small parts like below:$1234567 \times 23456 = 1234567 \times (20000+3000+400+50+6)$                                  $= 1234567 \times 20000 + 1234567 \times 3000 + 1234567 \times 400 + 1234567 \times 50 + 1234567 \times 6$                                  $= 24691340000 + 3703701000 + 493826800 + 61728350 + 7407402$                                  $= 28958003552$.The value of $1234567 \times 23456$ is $2895800355$

Given: $(7x\ -\ 6y)(6x\ -\ 7y)$To do: Here we have to simplify the given expression $(7x\ -\ 6y)(6x\ -\ 7y)$.Solution:$(7x\ -\ 6y)(6x\ -\ 7y)$$=\ 7x(6x\ -\ 7y)\ -\ 6y(6x\ -\ 7y)$$=\ 42x^{2} \ -\ 49xy\ -\ 36xy\ -\ 42y^{2}$$=\ \mathbf{42x^{2} \ -\ 85xy\ -\ 42y^{2}}$So, answer is 42x^{2} \ -\ ...
