2*2 = 4/1 and .4 = 4/10 are possible solutions.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
I can see no rational expression below.
A polynomial expression is considered a rational expression when it is expressed as a fraction where both the numerator and the denominator are polynomials. For example, the expression ( \frac{x^2 + 3x + 2}{x - 1} ) is a rational expression because its numerator ( x^2 + 3x + 2 ) and denominator ( x - 1 ) are both polynomials. Rational expressions can be simplified, added, or multiplied, just like rational numbers, provided that the denominator is not zero.
To determine what expression is rational to 01.05 MC, we need to understand that rational expressions consist of a ratio of two polynomials. For example, a rational expression could be ( \frac{2x + 3}{x - 1} ) or ( \frac{x^2 - 4}{x + 2} ). Specifically, if "01.05 MC" refers to a specific quantity in a context, we would need more details about that context to provide a precise rational expression.

An expression produces a rational number when its value can be expressed as a fraction ( \frac{a}{b} ), where ( a ) and ( b ) are integers and ( b \neq 0 ). For example, the expression ( 3 + 2 ) evaluates to ( 5 ), which is rational, as it can be represented as ( \frac{5}{1} ). Similarly, any expression involving addition, subtraction, multiplication, or division of rational numbers (as long as division by zero is avoided) will yield a rational result.

Radical expressions and expressions with rational exponents are closely related because they represent the same mathematical concepts. A radical expression, such as √x, can be rewritten using a rational exponent as x^(1/2). Similarly, an expression with a rational exponent, like x^(m/n), can be expressed as a radical, specifically the n-th root of x raised to the m-th power. This interchangeability allows for flexibility in simplifying and manipulating expressions in algebra.
