Question

25450 expressed in standard form is​

Answer 1

$2.5$×$10^{4}$ is the standard form of $25450$

Standard form

Any number that we can compose as a decimal number, somewhere in the range of 1.0 and 10.0, multiplied by a power of $10$, is supposed to be a standard form.

For example: standard form of $100$ is $1.0$×$10^{2}$

In the question given we have to find the standard form of $25450$

$25450=2.5$×$10^{4}$

Answer 2

Answer:

The standard form of 25450 is 2.545 × 10^4.

Explanation:

All numbers in scientific notation are in the form a × 10^b. Where b is an integer and the coefficient a is an absolute non-zero real number from 1 to 10. To convert the

25450 to scientific notation (also known as standard form), follow these steps:

• Move the number after the decimal point four times to the left so that the resulting number m = 2.545 is greater than or equal to 1 and less than 10.

• The exponent n is positive because the decimal point has been shifted to the left ( n = 4)

• In scientific notation, write m × 10^n,  = 2.545 × 10^4

Therefore,  in scientific notation, 25450 is 2.545 x 10^4 and has 4 significant digits.

In E-scientific notation, it is written as 2.545e + 4.
