Answer: The value of [tex]3a^2+4b^2[/tex] is 48.
Step-by-step explanation:
Since we have given that
[tex]3a^2+4b^2[/tex]
Here, a = 2
b = 3
So, we put the values of a and b in given expression:
So, Value of above expression would be
[tex]3(2)^2+4(3)^2\\\\3\times 4+4\times 9\\\\=12+36\\\\=48[/tex]
Hence, the value of [tex]3a^2+4b^2[/tex] is 48.
