3) 2.16*10^7

4) 1.524 * 10^7

Step-by-step explanation:

1) This number is less than 0, so the power will be negative. There are 6 0s after the 0, and then you also include the decimal place to the right of the 5, giving 7 decimal places to the right. So, the answer is 5.64 * 10^-7

2) Same technique as 1)

3) this time it is larger than 0, so the power will be positive. There are 7 places to the left of the decimal point, before the first number, in this case, 2. So, the answer will be 2.16 *10^7

4) Same technique as 3)
