Hello! Can someone explain Scientific Notation in math? Thank you so so much!

Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits. An example of scientific notation is when you write 4 x 10³ for 4,000. noun. 7. 0.

Step-by-step explanation:

B.

-8x^7+4x^3+4x+5

There's no way to get rid of or make smaller the 4x^3 and the -8x^7, since there are no other like exponents in the polynomial. B is the only one with a -8x^7
