Answer:
25m^3n^7
Step-by-step explanation:
Let's write out the equation
5mn^4 • 5m^2n^3
When we multiply exponents with similar bases, you add them together.
For example 2^2 • 2^2= 2^4
Numbers with no exponent are to the power of one
For example: 2= 2^1
Now that we know this, let's combine like terms
5 • 5=25
m^1•m^2=m^3
n^4•n^3=n^7
Answer: 25m^3n^7
