It’s not a polynomial

A polynomial is a combination of terms separated by + + or − -signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms.

If Tom has 3 different sweaters, and 5 different pairs of pants, how many different combinations could he wear?
Vladimir [108]
Check the tree diagram in the picture.

Tom could pick Pants 1 (P1), then Sweater 1, 2 or 3. So 3 combinations

Similarly if we picked P2, P3, P4 or P5 we would have 3 combinations per each.

In total we have 5*3=15 different combinations.

hope this helps! ❤  from peachimin

i attached this image which is sorta similar to the the to this equation:
