Answer :
Answer:
36
Step-by-step explanation:
(7+[tex]\sqrt{13[/tex] )(7-[tex]\sqrt{13[/tex] )
this is in the form of a^2-b^2 formula
a^2-d^2=(a-b)(a+b).so write,
(7)^2-([tex]\sqrt{13[/tex] )^2
=49-13
=36
[tex] \huge \mathrm{ \underline{Answer : }}[/tex]
The given expression can be written as :
- [tex]( 7 + \sqrt{13} )(7 - \sqrt{13} )[/tex]
- [tex](7) {}^{2} - ( \sqrt{13} ) {}^{2} [/tex]
[ by applying identity, (a+b) × (a-b) = a²-b² ]
- [tex]49 - 13[/tex]
- [tex]36[/tex]
Therefore, we will get 36 as our simplified answer.
