49 is 72 and is the closest square number to 50.
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
n = 157 157/7 = 22 remainder 3 or (22)(7) + 3 = 157 157/49 = 3 or (49)(3) = 157

45 is not a perfect square number. the closest perfect squares are 49 and 36. But it is the square of the irrational number 6.708204... (an infinite, non-terminating, non-repeating decimal).
9,408 is the closest number to the product of 192 and 49.
192 X 49 = 9408
49 is 72 and is the closest square number to 50.
It is: 47
No the nearest square number to it is 49
LCM of a prime number and a composite number is equal to their product if the latter is not divisible by the former. 5 is a prime number and 49 is a composite number. 49 is not divisible by 5. So, LCM(5,49) = 5 x 49 = 245. Actually the reason behind this is that both(5 and 49) do not share any common factors except 1, so the LCM is equal to the product.
It is: 246+(36*49) = 2010

No. The closest square numbers are 72 = 49 and 82 = 64.
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
Product (or multiplication) is a binary operator which means that you cannot have a product for only one number; you need two.
A composite number. The product of two primes is sometimes called a semiprime.
