A math problem that you don t know how to do, and a math problem that you can t do.

The right triangle can be simplified step by step.

To illustrate the above explanation, such problems should be triangulated into two corners and then merged with similar terms.

Your question is too misleading! Are there any parentheses?

Divide 2083 by 16 to take the remainder. Columns are vertically matched with such a line to stop: file orange beard.

Summary. The highest and lowest digits of the third set of products are the product of 9 and the second factor, and the middle three digits are 9 invariant.

Hello, you can send me the math problem and I'll show it to you.

Question 2. The highest and lowest digits of the third set of products are the product of 9 and the second factor, and the middle three digits are 9 invariant.

It's understandable if you take a look.

200000*a*[1+a] 120=, find the original formula of a: 200000*a*[1+a] 120=200000 about 200000, get a*[1+a] 120=, i.e. a*[1+a] 120=

Use on the web"Unary Higher Order Equation Calculator"Solution: a

This is the 121st order equation of a, and only an approximation of a can be found.

Let f(a)=200000*a*[1+a], then f(0)=0, let g(a)=f(a) a=200000(1+a), multiple!

Solution: Let there be x parts of type B and (x 12) parts of type A.

x＋4/5 （x+12）=42

5x+4（x+12）=210

9x+48=210

9x=162

x=18, so part 18+12=30 (pcs).

A: 30 parts A and 18 parts B.

Set x types of parts.

x*4/5+x-12=42

9x/5=54

x=30 30 for type A, 18 for type B.

Solution: If the production of type B parts is x, then the production of type A parts is (x+12) x+(x+12) 4 5=42

Solution: x=18

x+12=30

Answer: If the production of type A parts is 30, the production of type B parts is 18.

Column equation: A has x, B has y, then x-y=12,4 5*x+y=42, the solution is x=30, y=18

Solution: Set up a grandmother to raise x roosters.

3x-8=25

3x=33x=11

A: Grandma has 11 roosters.

At first glance, I didn't pay attention to the lectures.
