Question

i am not able to solve this problem​

Answer 1

First, 0.0004853 is < 1, so we need to multiply the number by 10 to a negative power if it's greater than 1 (if that makes sense i cant describe it better)

So, b and c is incorrect.

10 to the power of negative 4 = 0.0001, and 4.853 x 0.0001 = 0.0004853 (true), so answer is a

Answer 2

Answer:

a

Step-by-step explanation:

a number expressed in standard form is

a × $10^{n}$

where 1 ≤ a < 10 and n is an integer

given

0.0004853 ( place the decimal point after the 4 )

= 4.853 × $10^{n}$

to place the decimal point in its original position we require to shift it 4 places left , denoted by - 4 on the exponent , that is

0.0004853 = 4.853 × $10^{-4}$
