Question

simplify? solve the problem?​

Answer 1

Answer:

19

Step-by-step explanation:

(7√3-8√2)(7√3+8√2)                                (a-b)(a+b)=a²-b²

=>(7√3)² - (8√2)²

=> 147 -  128

=> 19

                 HOPE THE ANSWER IS  CORRECT.            

Answer 2

Answer:

Using identity=

a²-b²= (a-b)(a+b)

$( {7 \sqrt{3} - 8 \sqrt{2}})({7 \sqrt{3} + 8 \sqrt{2}})$

=$({{7 \sqrt{3}}})^{2} - ({8 \sqrt{2}})^{2}$

=(49×3)-(64×4)

=147-256

= -109
