Full solution

Q. Write the number 2.2×10−4 2.2 \times 10^{-4} in standard form.\newlineAnswer:\newline
  1. Understand Standard Form: Understand the meaning of standard form. Standard form means writing the number without using exponents, so we need to convert 2.2×10−42.2 \times 10^{-4} into a decimal number.
  2. Move Decimal Point: Move the decimal point in 2.22.2 to the left 44 places because the exponent is −4-4. Moving the decimal point 44 places to the left gives us 0.000220.00022.
  3. Check for Errors: Check for any mathematical errors in the conversion.\newlineThe decimal point was correctly moved 44 places to the left, which is consistent with the exponent of −4-4. There are no mathematical errors in this step.
