Write the number 2.2 ×10^(-4) in standard form. Answer:

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^(-4) into a decimal number.Move Decimal Point: Move the decimal point in 2.2 to the left 4 places because the exponent is -4. Moving the decimal point 4 places to the left gives us 0.00022.Check for Errors: Check for any mathematical errors in the conversion. The decimal point was correctly moved 4 places to the left, which is consistent with the exponent of -4. There are no mathematical errors in this step.

in standard form.

\newline

Answer:

\newline

Understand Standard Form: Understand the meaning of standard form. Standard form means writing the number without using exponents, so we need to convert $2.2 \times 10^{-4}$ into a decimal number.
Move Decimal Point: Move the decimal point in $2.2$ to the left $4$ places because the exponent is $-4$ . Moving the decimal point $4$ places to the left gives us $0.00022$ .
Check for Errors: Check for any mathematical errors in the conversion. $\newline$ The decimal point was correctly moved $4$ places to the left, which is consistent with the exponent of $-4$ . There are no mathematical errors in this step.
