What are the 3 rules for writing numbers in standard form?

Standard form is a way to write large, or small numbers. It takes a standard format (hence the name) of *.*** x 10^* so

3000 is written as 3 x 10^3

0.00045 is written as 4.5 x 10^-4

One digit in front of decimal point

To increase power move dot to right or number to left

To decrease power move dot to left or number to right

standard form is written in the form Z * 10^n

1) Z has to be between 1 and 10

2) standard form has a base 10

3) the power (n) has to be a whole number

The first number has to be between 1 and 10 but less than 10

It is always x 10 to the power of n

n has to be an integer

1.It should be in the form of Ax+By=C

2.A,B, and C must be integers

3.A cannot be zero

Standard Form is written in the form a x 10^n, where a is between 1 and 10 (greater than or equal to 1 but less than 10) and where n must be a whole number (positive or negative).

Example:

Correct: 3.5 x 10^3 or 2 x 10^-6

Wrong 0.3 x 10^2 or 13.4 x 10^5

A number is in standard form when it’s of the form:

a x 10^b where,

a is between 1 and 10 (inclusive of 1 but not 10), and b is an integer.

The a part is usually quite easily determined, however, the b part must be taken care of when converting ordinary numbers to standard form. Count how many spaces the decimal point has moved across to figure out the correct power of 10.

For example,

543,000 in standard form is 5.43 x 10^5.

0.00000678 in standard form is 6.78 x 10^-6.

Standard form is a way of writing down very large or very small numbers easily. 10 to the power of 3 = 1000, so as 4 × 10 to the power of 3 = 4000.

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.

For example, take the number 123000000, an easier way of writing this number is ​​

1.23 × 108.

First number between 1 and less than 10. Power should be an integer

The rule when writing a number in standard form is that first, you write a number between 1 and 10, then you write × 10 (to the power of a number). Type in the first number (the one between 1 and 10). Press EXP. Type in the power to which the 10 has risen.
