Question

Explain the numbers in standard
form​

Answer 1

Answer:

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . ... 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).

Answer 2

Answer:

for example,

12345 is there

=1×10000+2×1000+3×100+4×10+5×1.

= 10000+2000+300+40+5

=12345.

we should add with multiplication.
