Example of subtracting monomials with exponents.

Subtract the following monomials with exponents

54v5 - 50v5 - 4w5

Solution.

Here 54v5 and 50v5 are like terms (monomials). We can subtract them

54v5 - 50v5 = 4v5

The 4v5 and 4w5 are unlike terms (monomials). We cannot subtract them.

54v5 - 50v5 - 4w5 =
4v5 - 4w5

The answer 4v5 - 4w5.

See the definition of unlike terms.
