Answer:
The correct option is 4.
Step-by-step explanation:
The given expression is
[tex](2x^2y^6z^5)(5x^4y^5z^3)[/tex]
Simplify the given expression.
[tex](2x^2y^6z^5)\times (5x^4y^5z^3)[/tex]
[tex](2\times 5)(x^2x^4)(y^6y^5)(z^5z^3)[/tex]
[tex]10x^{2+4}y^{6+5}z^{5+3}[/tex] [tex][\because x^mx^n=x^{m+n}][/tex]
[tex]10x^6y^{11}z^8[/tex]
Therefore correct option is 4.
