1A) Degree: 3
1B) 4 terms
1C)![7x^3-5x^2-4x+10](/tpl/images/0507/4138/1573a.png)
2A)![3m-5n+1](/tpl/images/0507/4138/23257.png)
2B)![-2b^3-3b+3](/tpl/images/0507/4138/86544.png)
Step-by-step explanation:
The given polynomial is![-4x+7x^3-5x^2+10](/tpl/images/0507/4138/069c3.png)
Let us rewrite the polynomial in decreasing powers of x.
This gives us the expression;
So let us answer the question:
A) The degree is the exponent of the first term when the polynomial is written in standard form.
Degree: 3
B) The terms are separated by + or - signs.
Number of terms: 4
C) Standard form:![7x^3-5x^2-4x+10](/tpl/images/0507/4138/1573a.png)
2A) The given expression is![(7m-2n)+(-3n-4m+1)](/tpl/images/0507/4138/db3b9.png)
We expand using the distributive property to get:
We regroup the terms to get:
We simplify to obtain:
2B) The given expression is![(b^3-2b+4)-(3b^3+b-1)](/tpl/images/0507/4138/00c4a.png)
Regroup the terms to get:
We simplify to get:
Ответ:
p^7
Step-by-step explanation:
When multiplying exponents with the same base, all you have to do is add the exponents together.
This means...
p^3 x p^4 is basically...
3 + 4 = 7
so it's p^7
Hope this helps :)
