Question

if degree of 9 x pwer 5 y power 2 z power r is 15 then r is equal to​

Answer 1

Answer:

SOLUTION

GIVEN

The degree of 9x⁵y²zr is 15

TO DETERMINE

The value of r

CONCEPT TO BE IMPLEMENTED

Polynomial

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

Degree of a Polynomial

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.

EVALUATION

Here the given polynomial is

9x⁵y²zr

From above we can conclude that

The degree of 9x⁵y²zr

= 5 + 2 + r

= 7 + r

So by the given condition

7 + r = 15

⟹r = 8

FINAL ANSWER

Hence the required value of r = 8

Answer 2

Answer:

15/90xyz =1/6xyz

when we multiply the LHS we get 90 xyz.then transpose it .it becomes 15/90xyz

and on simplifing it the answer is 1/6xyz
