-2y^2 * xy^4

When the bases are the same, you can combine the exponents.

x³   [x is where the base is]

For example:

x³ · y² = x³y²   You can't simplify this anymore because they have different bases/variables

[when you multiply a variable with an exponent by a variable with an exponent, you add the exponents together] so:

x² · x³ =

[when you multiply a variable with an exponent by an exponent, you multiply the exponents together] so:

(x³)²=

Step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
