Step 3: Write the non-zero digit and the decimal places as a number between 1 and 10 (inclusive) and multiply it by 10 raised to the power of the number of decimal places.
2.5437 x 10^(-5)
To express a number in scientific notation, we need to represent it as a number between 1 and 10 multiplied by a power of 10. In this case, we have the number 0.000025437.
To write this number in scientific notation, we can begin by identifying the non-zero digits, which in this case are 2, 5, 4, 3, and 7. Next, we count the number of decimal places we need to move the decimal point to obtain a number between 1 and 10. In this case, we need to move the decimal point 5 places to the right.
Since we are moving the decimal point to the right, the exponent of 10 will be negative. Therefore, the scientific notation for 0.000025437 is 2.5437 x 10^(-5).
