Answer:
Your answer should be A) 25^15
Step-by-step explanation:
Multiply your bases (5*5) to get your main base of 25.
Add your exponents (4+11) to get your base exponent of 15.
[tex]5^{15}[/tex]
In exponents multiplication, if bases are same, just add the powers.
[tex]a^{m}*a^{n}=a^{m+n}\\\\5^{4}*5^{11}=5^{4+11}=5^{15}[/tex]
