Remember that exponentioal rule
x^m times x^n=x^(m+n)
therefor
7^4 times 7^-6=7^(4-6)=7^(-2)
remember the other rule
x^-m=1/(x^m) so
7^-2=1/(7^2)=1/49
answe ris A
They are similar triangles because they are both right triangles
Inequalities are used to compare unequal expressions.
The actual comparison is:
or 
The temperatures are given as:
From the above list, we have:
By comparison,
or
Using absolute values, the inequalities are:
or 
Hence, the actual comparison is:
or

Answer:
x⁵ +2x³ -3x², degree 5, 3 terms
Step-by-step explanation:
We assume you intend your expression to be ...
2x³ -3x² +x⁵
The superscript numbers are exponents. Each indicates the degree of the term. In standard form, terms are listed in decreasing order by degree:
x⁵ +2x³ -3x² . . . . standard form
The degree of the polynomial is the degree of the highest-degree term: 5.
The number of terms is the number of products in the sum: 3.
