5mn^4 • 5m^2 n^3<br><br>Does that even makes sense <br><br>​
xeze [42]

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
