First of all, we know that polynomial is an eighth-order trinomial, and find the value of n.
Second, subtract a polynomial to get this polynomial.
Both Company A and Company B are ready to recruit talents from the society. The recruitment conditions of the two companies are basically the same, except for the following differences in salary: Company A promises an annual salary of 1 10,000 yuan, and the annual processing age salary is 200 yuan; Company B promises a salary of 5000 yuan for half a year, which company is more favorable from the perspective of economic income.
Fourth, the value of knowing.
5. it is known to find out the relationship between a, b and C.
6. Given 10a = 5 and 10b = 6, find the value of 102a+3b.
7. Given 3m = 6 and 9n=2, find the value of 32m-4n+ 1.
Eight, known, find the value of algebraic expression.
9. (1) If, simplify; (2) If, simplify.
Ten, calculation has the following kinds:
( 1):(2+ 1)(22+ 1)(24+ 1)? 6? 1(28+ 1); (2):(a+ 1)(a2+ 1)(a4+ 1)……(a 100+ 1)。
(3): known, the value of; (4): known, the value of;
(5): Known, find the value of xy.
(6):, and the natural numbers x and z satisfy 2x? 6? 13z- 1 = 72, and find the value of m.
(7):(x2+x-2)÷(x- 1).
