Is 12 over 18 a rational or irrational number?
The fraction 12/18 can be simplified to 2/3 by dividing both the numerator and denominator by their greatest common divisor, which is 6. Since the fraction 2/3 can be expressed as a ratio of two integers and can be written in the form a/b where a and b are integers and b is not equal to 0, it is considered a rational number. Rational numbers are numbers that can be expressed as a ratio of two integers.
Factor a cubed plus B-Cubed?
The expression a^3 + b^3 can be factored using the sum of cubes formula, which states that a^3 + b^3 = (a + b)(a^2 - ab + b^2). Therefore, a^3 + b^3 can be factored as (a + b)(a^2 - ab + b^2). This formula helps us break down the sum of two cubes into a product of binomials, simplifying the expression.
What are the rules on factoring polynomials with common monomial?
In order to successfully factor you should follow these steps: 1.) Take out the GCF (ALWAYS DO THIS FIRST) 2.) Diff of Perfect Squares a^2-b^2=(a+b)(a-b) 3.) Diff/Sum of Cubes a^3+b^3=(a+b)(a^2-ab+b^2) a^3-b^3=(a-b)(a^2+ab+b^2) 4.) Key Number 5.) Grouping
A and b are prime numbers ab3 equals 54 find the values of a and b?
54 = 2 x 3 x 3 x 3 = 2 x 33. Thus if ab3 = 54 and a, b are prime, then a=2, b=3.
What is the general form of a complex number?
a + i b, with a and b real numbers and i = sqrt(-1)
How would you write bxbxbxbxbxb in short index form its a maths question?
To write ( bxbxbxbxbxb ) in short index form, you can group the terms. Since there are six ( b )s multiplied together, you can express it as ( b^6 ). Therefore, the short index form of ( bxbxbxbxbxb ) is ( b^6 ).
What is B over 3 plus b over 3 as math answer?
It is (B + b)/3.
What is the answer of a over b when a is 2 over 3 and b is 3 over 4?
8/9
What is B over B in simplest form?
1
What is b. b over 5 plus b over 3 equals 10?
If: b/5+b/3 = 10 then b works out as 18.75
If a over b equals 3 over 4 then 4 over 3 equals what?
answer: b over a for ur question: if, a/b = 3/4 then, 4/3 = ? when u switch the place holders like that, it is called the 'inverse'. and since 4/3 is the inverse of 3/4, then the inverse of a/b is b/a.
What is the simplest form of b over bc?
Assuming bc stands for b*c and not 10b+c (as in 35 can stand for 3*10+5), the answer is 1/c
Is 3 over 4 x b the same as 3xb qver 4?
It is difficult to answer the question because it is still ambiguous. Putting brackets in helps. So: (3 over 4) x b = 3/4*b = 3*b / 4 YES but 3 over (4 x b) = 3/(4*b) is not 3/4*b
What cannot be expressed in the form a over b?
An irrational number cannot be expressed in form of a/b.
What is 20 over 60 on simplest form?
20 over 60 is the same as 2 over 6. And 2 over 6 is the same as 1 over 3. B-EHS
Is 3 over 5 a rational or irrational number?
3 over 5 is a rational number because it can be expressed as a fraction of two integers, where 3 is the numerator and 5 is the denominator. Rational numbers are defined as numbers that can be written in the form ( \frac{a}{b} ), where ( a ) and ( b ) are integers and ( b ) is not zero. Since both 3 and 5 are integers and 5 is not zero, 3 over 5 is indeed rational.
What is 1 over x 3 over a 2 over b?
b/6
