Answer:
The correct option is C [tex]7^{11}[/tex]
Step-by-step explanation:
Consider the provided expression.
[tex]7^6\cdot 7^5[/tex]
Use the property of exponent: [tex]a^m\cdot a^n =a^{m+n}[/tex]
By using the above property we can simplify the provided expression as shown:
[tex]7^6\cdot 7^5[/tex]
[tex]7^{6+5}[/tex]
[tex]7^{11}[/tex]
Now simplify it further,
[tex]7^{11}[/tex]
Hence, the correct option is C [tex]7^{11}[/tex]
