# Is 6000 a prime numbers?
## Is 6000 a prime numbers?
Prime Numbers Before Calculator The number 6000 is not a prime number because it is possible to express it as a product of prime factors. In other words, 6000 can be divided by 1, by itself and at least by 2, 3 and 5. So, 6000 is a ‘composite number’.

Introduction
• In general, the ratio of a number x to a number y is defined as the quotient of the numbers x and y.
• Ratios can be expressed as percentages. To express the value of a ratio as a percentage, we multiply the ratio by 100.
Thus, 4/5 = 0.8 = 80%
Some Important Properties

xWhat is x if lg(2x+2)=lg(8+3x)/(x-2)?
justaguide | Certified Educator
We have to solve lg(2x+2)=lg[(8+3x)/(x-2)]
Equate 2x + 2 = (8+3x)/(x-2)
=> (2x + 2)(x - 2) = 8 + 3x
=> 2x^2 + 2x - 4x - 4 = 8 + 3x
=> 2x^2 - 5x - 12 = 0
=> 2x^2 - 8x + 3x - 12 = 0
=> 2x(x - 4) + 3(x - 4) = 0
=> (2x + 3) = 0 and (x - 4) = 0
