Final answer:
To express 0.0053 in standard form, move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. Therefore, 0.0053 in standard form is 5.3 x 10-3.
Step-by-step explanation:
To express 0.0053 in standard form, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. Since 0.0053 is less than 1, we will be moving the decimal point in the positive direction.
We start by moving the decimal point one place to the right, giving us 0.053. Next, we move the decimal point one more place to the right, resulting in 0.53. Finally, we move the decimal point one more place to the right, giving us 5.3. Therefore, 0.0053 in standard form is 5.3 x 10-3.
