How do you turn 0.000619 into scientific notation

I think it 6.1x10^4

6.19*10^-4 because you are moving the decimal to the left 4

0.000 000 000 074 61 = 7.461 × 10^(-11)

A number in scientific notation has the form N × 10^a where

N = the coefficient and 1 ≤ N <1  and

a = the exponent and is an integer

Step 1. Find the coefficient.

Move the decimal point to the right until you get a coefficient between 1

and 10.

The coefficient becomes 7.461.

Step 2. Determine the exponent.

The exponent is the negative of the number of places you moved the decimal point.

You had to move the decimal point 11 places, so the exponent is -11.

Step 3. Write the number in scientific notation.

0.000 000 000 074 61 = 7.461 × 10^(-11)

4.0506100 x 10^-1

Step-by-step explanation:

Because all you need to do is move the decimal point to the right once, you write 10^-1 to show that to get back to the original number, you just multiply 4.0506100 by -0.1

6.1 x 10^-2

this is the answer because the first number has to be in between 1-10. Then you work from there and get 6.1 x 10^-2

6.125 × 10^-5

Explanation:

You have to move the decimal place 5 times to the right. Remember in scientific notation the first number, (the number that comes before the 10) has to be between 1.0 and 9.99...

6.1x10^-2

Step-by-step explanation:

First come up with the decimal number

7.461

Then determine how many times the decimal point needs to move

7.461

0.7461

0.07461

... and you keep going and end up moving the point 11 times

so the answer is 7.461ˣ, where x=11

i couldn't figure out how to write 7.461 to the 11th power...

Your answer is 6.1 • 10^-1
