All positive numbers have a square root, and a square root is defined as the number you can multiply by itself to get the original number.

In this case 9 x 9 = 81, which means that 9 is a square root of 81. However, if you multiply two negative numbers, you get a positive number. This means that every positive number has a square root that is positive and negative.

-9 x -9 = 81

The answer is -9 and 9

Determine if the expression 9y5 – 10y3 is a polynomial or not. If it is a polynomial,

Stolb23 [73]

I am going to assume that the equation was supposed to be $9y^{5}$ $-10y^{3}$

Answer:

It is a polynomial. It is a binomial and it has a degree of 5.

Step-by-step explanation:

A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables so $9y^{5}$ $-10y^{3}$ will be considered a polynomial.

A binomial is a polynomial with 2 terms.

The degree of a polynomial is the highest exponent in it which in this equation is 5.
