Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like . Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial, , which equals .
- Then, the outside terms, . This equals .
- Next, the inside terms, .
- Finally, the last terms, , this equals .
Then, add all of the terms together . To get the standard form, combine like terms, this comes out to .
The difference between m and r from the given expressions is 8
<h3>Indices and exponents</h3>
Given the following exponents
x^m/x^5=x^7
x^m = x^5 * x^7
x^m = x^12
Equate the powers
m = 12
For the expression
(x^r)³ = x^12
x^3r = x^12
3r = 12
r = 4
Take the difference
m - r = 12 - 4
m - r = 8
Hence the difference between m and r is 8
