Answer: x = 1/2
Step-by-step explanation:
4x - 2x - 4 + 3
2x - 1
x = 1/2
Answer:
multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by xyields the multiplicative identity, 1.
remember that to put a number in scientific notation is necessary to have the first digit of the number different to 0, so

to calculate the order of magnitude, if the number is greater than 3.16, we assume it as a 10, so in this case as 7.654 > 3.16 we get that the order is

So the order is 10^-3
