how do u change 0.015 from standard form to scientific notation [ please don't charge me money im only 11 yrs old trynna get help with my homework ]
Jiskha never charges anyone for getting help!
You must really be in an advanced class to have this problem.
0.015 = 1.5 * 10^-2

No worries! I'm here to help explain how to change a number from standard form to scientific notation, and it won't cost you anything. Let's go step by step:
Step 1: Write down the given number (0.015).
Step 2: Move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. Count the number of places you moved the decimal point.
- In this case, you would move the decimal point three places to the right, resulting in the number 1.5.
Step 3: Rewrite the remaining digits (1.5) as a decimal number between 1 and 10.
- In this case, it is 1.5, which is already between 1 and 10.
Step 4: Write the power of 10 by using the number of places you moved the decimal point in step 2. If you moved the decimal point to the right, the exponent is negative. If you moved the decimal point to the left, the exponent is positive.
- Since we moved the decimal point three places to the right, the exponent is -3.
Step 5: Combine the decimal number from step 3 and the power of 10 from step 4 to write the number in scientific notation.
- In this case, it is written as 1.5 × 10^(-3).
So, 0.015 in scientific notation is 1.5 × 10^(-3). Keep up the great work!
