In scientific notation, just move the decimal point over however many numbers are in the power.
In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030
![y = 2 {x}^{3} - 7 {x}^{2} + 2x + 3](https://tex.z-dn.net/?f=y%20%3D%202%20%7Bx%7D%5E%7B3%7D%20%20-%207%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20%2B%203)
By inspection 1 is a root of y ,
Hence , (x-1) is a factor of y ,
![\dfrac{2 {x}^{3} - 7 {x}^{2} + 2x + 3 }{x - 1} = 2 {x}^{2} - 5x - 3 \\ \\ 2 {x}^{2} - 5x - 3 = (2x + 1)(x - 3)](https://tex.z-dn.net/?f=%20%5Cdfrac%7B2%20%7Bx%7D%5E%7B3%7D%20-%207%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20%2B%203%20%7D%7Bx%20-%201%7D%20%20%3D%202%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20-%203%20%5C%5C%20%20%5C%5C%202%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20-%203%20%3D%20%282x%20%2B%201%29%28x%20-%203%29)
Hence , the 2 other roots are -1/2 and 3 , and the above graphs confirms the same.
Hope it helps you :)

Answer:
the statement which is not true is
~All Irrational Numbers are real Numbers
I believe it to be 4 because 3=24/8
So 5/8 + 5/8 = 10/8 + 5/8 = 15/8 + 5/8 = 20/8 + 5/8 = 25/8, which is the closest number to 3
