√2 ≈ ?
Explanation
The given value of 1.4 is an approximation of the square root of 2. The square root of 2 is an irrational number, meaning it cannot be expressed as a fraction or a terminating or repeating decimal. The decimal representation of the square root of 2 goes on infinitely without a pattern. However, 1.4 is a close approximation of the square root of 2 and is commonly used in calculations where an exact value is not necessary.Rate this question:

RatioIsoceles∆ Sides? (answer format x:y:z√ = option+v)
Explanation
The given answer, 1:1:√2, represents the ratio of the sides of an isosceles triangle. In an isosceles triangle, two sides are equal in length, and the third side, which is the base, may have a different length. The ratio 1:1:√2 indicates that the two equal sides have a length of 1 unit each, while the length of the base is √2 units. This ratio is commonly used to describe the sides of a 45-45-90 degree triangle, where the two equal angles are 45 degrees each and the right angle is 90 degrees.Rate this question:

Complete the ratioRight∆:3:4:x
Explanation
The ratio is given as 3:4:x. To find the value of x, we can set up a proportion using the given information. The ratio of the first two terms is 3/4, and the ratio of the second and third terms is 4/x. We can cross multiply and solve for x. 3x = 4*4, which simplifies to 3x = 16. Dividing both sides by 3, we get x = 16/3. However, since the answer is given as 5, it does not match the calculated value. Therefore, the question may be incomplete or the given answer may be incorrect.Rate this question:

0!=?
Explanation
The value of 0! (0 factorial) is 1. Factorial is a mathematical operation that multiplies a given number by all the positive integers less than it. By convention, 0! is defined as equal to 1. This is because there is only one way to arrange zero objects, and that is by not arranging them at all. Therefore, the answer to 0! is 1.Rate this question:
- 30.
1!=?
Explanation
The factorial of a number is the product of all positive integers less than or equal to that number. In this case, 1! (read as "1 factorial") is equal to 1 because there is only one positive integer less than or equal to 1, which is 1 itself. Therefore, the answer is 1.Rate this question:
- 31.
2!=?
Explanation
The question is asking for the factorial of 2, which is denoted by 2!. The factorial of a number is the product of all positive integers less than or equal to that number.

Factor (x+y)2(Note: x2 = x2)
Explanation
The given expression is asking for the square of the sum of x and y. To find this, we use the formula (a+b)2 = a2 + 2ab + b2. In this case, a is x and b is y. Plugging in these values, we get x2 + 2xy + y2 as the correct answer.Rate this question:
- 38.
Factor (x-y)2(Note: x2 = x2)
Explanation
The given expression is (x-y)², which represents the square of the difference between x and y. Expanding this expression using the formula (a-b)² = a² - 2ab + b², we get x² - 2xy + y². Therefore, the correct answer is x² - 2xy + y².Rate this question:
- 39.
Factor (x+y)(x+y)(Note: x2 = x2)
Explanation
The given expression (x+y)(x+y) can be expanded using the distributive property. Multiplying each term in the first set of parentheses by each term in the second set of parentheses, we get x*x + x*y + y*x + y*y. Simplifying this further, we combine like terms to obtain x^2 + 2xy + y^2. Therefore, the correct answer is x^2 + 2xy + y^2.Rate this question:
- 40.
Factor (x+y)(x-y)(Note: x2 = x2)
Explanation
The given expression is a product of three terms: (x+y), (x-y), and (x2-y2). The first two terms can be expanded using the difference of squares formula, which states that (a+b)(a-b) = a2-b2. Applying this formula to (x+y)(x-y) gives us x2-y2. Therefore, the correct answer is x2-y2.Rate this question:
