Answer:
[tex]D) 7[/tex]
Step-by-step explanation:
[tex]a^{2} -2b^{2}[/tex]
[tex]a=5[/tex]
[tex]b=3[/tex]
[tex]\left(5\right)^2-2\left(3\right)^2[/tex]
Calculate 5 to the power of 2 and get 25:-
[tex]25-2\times 3^{2}[/tex]
Calculate 3 to the power of 2 to get 9 and then multiply 2 and 9 to get 18:-
[tex]25-18[/tex]
[tex]=7[/tex]
