A=5.26,n=26 but please i need the workings please
To find A and n we need to move the decimal place of the number 0.000005257 to the right until we get a number between 1 and 10.
We start by moving the decimal point 1 place to the right:
0.000005257 x 10 = 0.00005257
This number is still not between 1 and 10, so we move the decimal point one more place to the right:
0.000005257 x 100 = 0.0005257
This number is still not between 1 and 10, so we move the decimal point one more place to the right:
0.000005257 x 1000 = 0.005257
This number is between 1 and 10, with A = 5.257. To get n, we count the number of places we moved the decimal point to the right. We moved it 4 places, so n = -4.
Therefore, 0.000005257 = 5.257 × 10^-6 in scientific notation.
