Final answer:
To express 1.89263×10⁴ in standard form, move the decimal 4 places to the right, resulting in 18926.3.
Step-by-step explanation:
The student has asked to convert the number 1.89263×10⁴ into standard form. To do this, we need to move the decimal point to the right as many places as the exponent on 10 indicates. Since we have 10 to the fourth power (×10⁴), which means 10 multiplied by itself 4 times, we move the decimal place 4 times to the right. 1.89263×10⁴ becomes 18926.3 in standard form. This process of moving the decimal point changes the scientific notation to a full number without an exponent, making it much easier to read and understand.
