1, simplest fraction: numerator and denominator have no common factor and are coprime.
2. The simplest decimal: there is no 0 at the end of the decimal.
3. The simplest algebraic expression: merging similar items in algebraic expressions.
4. The simplest fraction: the denominator of the fractional numerator has no common factor.
. .
Question 2: The simplest form in mathematics requires a polynomial to be decomposed into the products of several simplest algebraic expressions in an interval (such as rational numbers, that is, all terms are rational numbers). This deformation is called factorization, also called factorization. It is widely used in drawing mathematical roots.
Principle:
1, the decomposition must be thorough (that is, the factors that can no longer be decomposed after decomposition)
2. Only brackets are left at the end of the result.
3. The first polynomial term of the result is positive. Extract its common factor from the formula, that is
Recombine according to the formula, and then extract the common factor.
4. The first number in brackets cannot be preceded by a negative sign;
5. If the monomial is multiplied by the polynomial, the monomial should be placed before the polynomial. That is the form of a(a+b).
Question 3: What does this mathematical formula mean? √4=√2*2=2
√9=√3*3=3
2√4=2√2*2=2*2=43√5 is the simplest formula and cannot be simplified. 2√4 *3√5=4*3√5= 12√52√ 16=2*4=84√25=4*5=20
