Answer: 51+27=3(17+9)=78
Step-by-step explanation:
Since we know that the distributive law states that
[tex]a\times(b+c)=ab+ac[/tex]
So, we apply this on our expression which is given by
[tex]51+27\\\\=3\times (17+9)\\\\=3\times 26\\\\=78[/tex]
Hence using distributive property of 51+27 we'll get 78 in answer.
