Rewrite 9.98 × 10 7 in standard form.

Alright, guys. Let's get some practice taking this number here in scientific notation and we're gonna rewrite it in standard form. And remember, it all comes down to this exponent this over here. So we're gonna take this number, 9.98 and the exponent which is 7 tells us which which how many places to move the decimal. And if it's a positive exponent like we have over here, we're gonna end up with a number that's much bigger than 10. So in order to do that, we're gonna have to do is we're gonna have to shift the decimal place to the right 7 times. So we have to go 1, 2, 3, 4, 5, 6, 7. So this is 7 decimal places, and that's what the exponent tells us to do, and we're gonna fill in the zeros. And the last thing you do is have to just, like, separate all the 3, play every 3rd place with a comma. And so what we end up with is, we look through our answer choices. This is answer choice d. Let me know if you have any questions guys.

Verified step by step guidance

Understand that standard form, also known as scientific notation, is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

Identify the given number: 9.98 × 10⁷. This is already in scientific notation, where 9.98 is the coefficient and 10⁷ is the power of ten.

To convert this into standard form, multiply the coefficient by 10 raised to the power of 7. This means moving the decimal point in 9.98 seven places to the right.

Start by moving the decimal point in 9.98 one place to the right to get 99.8, then continue moving it six more places to the right, adding zeros as needed.

After moving the decimal point seven places, the number becomes 99,800,000, which is the standard form of the given scientific notation.
