We have the following expression:

$2x^2y\cdot3x^5y^2$

By combining similar terms, we get

$2\cdot3\cdot x^2\cdot x^5\cdot y\cdot y^2$

now, 2 times 3 is 6 and to add exponents, both the exponents and variables should be alike:

$x^2\cdot x^5=x^(2+5)=x^7$

Similarly,

$y\cdot y^2=y^(1+2)=y^3$

Therefore, the answer is
