Answer:
x^12
Step-by-step explanation:
When multiplying exponents, the rule below is followed.
[tex]x^a * x^b= x^{a+b}[/tex]
Basically, the base remains the same, but the numbers in the exponents are added.
We are given:
[tex]x^5*x^7[/tex]
We leave the base (x)as is, and add the numbers in the exponents (5 and 7).
[tex]x^5*x^7\\[/tex]
[tex]x^{5+7[/tex]
[tex]x^{12}[/tex]
The expression [tex]x^5*x^7\\[/tex] can be simplified as: [tex]x^{12{[/tex]
