A is twice efficient than B A and B can both work together to complete a work in 7 days Then find in how many days A alone can complete the work?
10.5 days how it comes : if a is twice as efficient than b that means ratio of time taken by A and B is :- 1:2 then 1/2x + 1 /x = 7 x=10.5

Can a least common multiple be found for any two natural numbers?
Short answer: Yes. Long answer: Explanation: lcm means least common multiple, gcd means greatest common divisor, |a| means the absolute of a, a / b means a divided by b, a * b means a multiplied by b Premise: Let a and b be a natural numbers, i.e. a ⋲ IN, b ⋲ IN. 1: It is known that lcm(a, b) = (|a| * |b|) / gcd(a, b) 2: Also the gcd of two numbers is at least 1, or in math: ∀ a ⋲ IN: gcd(a, b) >= 1. 3: From 1 and 2 we can conclude: lcm(a, b) = |a| * |b| / gcd(a, b) <= |a| * |b| 4: From 3 and the premise we can conclude (because ∀ a ⋲ IN: |a| = a): lcm(a, b) <= a * b 5: Now the product of two natural numbers (like a and b) is a natural number as well, or in math: ∀ a ⋲ IN, b ⋲ IN: a * b ⋲ IN 6: From 2 and 5 we can finally conclude, that: ∀ a ⋲ IN, b ⋲ IN ∃ c ⋲ IN: lcm(a, b) <= c
In the pythagorean theorem is b twice of a?
In the Pythagorean Theorem b is not twice a. The formula is [ a squared + b squared = c squared].
Why is the radical a2 b2 is not equal to a b?
Because a radical has two solutions, the positive and negative. This means that √(a2b2) has twice as many solutions as ab. ab is in fact a subset of √(a2b2).
What is the least common multiple of A and B?
The word "LEAST" (in Least Common Multiple) is a superlative adjective and that means there can be only one. So asking about least common multiples makes no sense.LCM(A, B) = A*B.

Product of twice a and b?
The product of twice "a" and "b" can be expressed as: 2ab In this expression, "a" and "b" are variables that represent numerical values. Multiplying "a" and "b" gives their product, and then multiplying the result by 2 gives twice that product.
In this parallelogram the measure of b is twice the measure of a what is the measure of B is twice the measure of A What is the measure of A?
The measure of A is 60.
