What does 'standard form' mean in maths, ks3 (level 8), ?

Answer 1

Say for instance you're talking about an equation of a straight line:

y = mx + b

That is in standard form.

The same equation re-arranged a little bit is not:

--> mx = y - b

--> b = y - mx

--> x = (y - b)/m

All of those are the same equation, and none are in 'standard form'.....only the very first one I gave you is in std frm.

Hope this helps.

Answer 2

Standard form of a number is the form when a number is expressed as a number between 1 and 10 and multiplied by 10^n where n is an integer.
Examples
148 = 1.48 x 10²
2754 = 2.754 x 10³
0.085 = 8.5 x 10^(-2)

Answer 3

Standard for is usually v large or v small numbers written as

a x 10^b

Where "a" is a decimal number between 1.0000 and 9.99999

And "b" is a whole number (negative for small numbers, positive for big numbers.

E.g. 0.000000134 becomes 1.34 x 10^ -7

and 734 000 000 becomes 7.34 x 10^ 8

The power number after the "10" if found by counting the number of places the decimal point is moved!! If moved left a minus number, if moved right a positive number.

Answer 4

To put things in standard form example 324 you need to first make the numebr less then 10.
so 3.24 would work.
Then to put in standard form you times it by 10 to the power- however many times you moved the number past the decimal point.
So the answer is 3.24 x 10^2

Another example is 0.007285
= 7.285 x 10^-3

Bit confusing but i hope it helped

Answer 5

It is a number in the form

a*10^n

where 1

Answer 6

eg. you have the number 5672. to put this in standard form you write it as 5.672 * 10 to the power of 3 ( not sure how to do powers on the computer)
basically you put a decimal point in to make the number between 0 and 10 and then write * 10 to the power of whatever number is needed to make the original number.
