Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
[tex]5a\times 5b[/tex]
We need to simplify the above expression:
First we gather the constant terms together and variables together.
And then multiply the constant term and variables.
[tex](5a)\times (5b)\\\\=(5\times 5)\times (a\times b)\\\\=25ab[/tex]
Hence, Second option is correct.
