900 in scientific notation is represented as 9 x 10^2. In scientific notation, a number is expressed as a coefficient multiplied by 10 raised to a certain power. In this case, 900 can be written as 9 (the coefficient) times 10 raised to the power of 2 (since 900 is equivalent to 9 x 100, which is 9 x 10^2).
Let the number be x and so the expression is 4x -3
