What is 8 in scientific notation

Step-by-step explanation: To write number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point. So here, we can think of 8 as 8.0.

Next, count the number of places that we would need to move the decimal point in order to get back to the original number.

The number of places that we would need to move the decimal point tells us our exponent.

Notice that 8.0 already has only one digit to the left of the decimal point. Therefore, we would need to move the decimal point 0 places to get back to the original number. Finally, scientific notation is written with a number between 1 and 10 which includes 1 but not 10. Also, that power is being multiplied by a power of 10.

So in this case, we have .

This answer should make sense because is equal to 1 and 8 × 1 is 8.

My work is also attached in the image provided.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
