Plz help me answer this

Answer 1

Answer:

B,C,D

Step-by-step explanation:

B.

(15/3)^x can be simplified to 5^x because 15/3 = 5 and the power remains same after we simplify

C.

$\frac{ {15}^{x} }{ {3}^{x} } = \frac{ {5}^{x} \times {3}^{x} }{ {3}^{x} }$

after rewriting the expression we can simplify 3^x from bottom and top so only 5^x remains.

D.

to multiply an exponential number you can add up their powers if their bases are same.
