11a 11ab 7, where a 2, b one-third?

Analysis: Substituting a=2, b=-one-third into 11a-11ab-7 obtains:

44+7 again, 1 3-7

44 and 1 3

Because a=2, b=-1 3, then a =2 =4, ab=2*(-1 3)=-2 3. Substituting them into the expression, we get 11*4-11*(-2 3)-7=44+7+(1 3)-7=44+1 3=133 3.

It is known that a = 2 and b = -3, and to bring in it is a = 4, 11ab = 11 2 (-3) = -66, so the original formula is equal to 4-(-66)-7 = 63

11a 11ab 7, where a 2, b one-third?

37 + 7 again 1 3

44 and 1 3

Hopefully, thank you

<> do the math to find the result.

This algebraic formula is calculated, which is equal to 44 and 1 3, and there is no possibility of simplification in this algebraic formula, so it is enough to substitute the values of a and b.

Solution: Because 1 a+1 b = 4

The score is a+b=4ab

Substitute what you seek, get.

Original formula = 4ab-3ab 2 (4ab) - 7ab = 1

Polynomial Collection:

Integer set: An equation that uses operator derivatives (referring to addition, subtraction, multiplication, division, multiplication, and opening square) to connect numbers or letters representing numbers is called an algebraic formula.

Algebraic formulas that only perform finite addition, subtraction, multiplication, division, and integer times multiplication operations for letters are called rational expressions (excluding open square operations, but can have irrational number constants, such as root number 2), and algebraic expressions containing radical expressions (and letters under the root number) are called irrational expressions.

A rational formula that only performs a finite number of addition, subtraction, multiplication, and integer times of power operations for letters is called an integer (excluding division operations, or the denominator is a constant); A rational expression that contains division (and the denominator has letters) is called a fraction.

Integers are divided into mononomials and polynomials; The form of the product of numbers and letters is called a monomial, and a single letter or number is also a monomial; The sum of several monomials is called a polynomial.

Answer: The original price of this set of clothes is 625 yuan 0

a/11+b/3=3a/33+11b/33=(3a+11b)/333a+11b=17

a=2 b=1

This question restricts ab to an integer, right?
