Question

Write
$15x^2+x^3-125y^3+75xy^2$
in standard form?
​

Answer 1

Answer:

Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).
