Question

What is 8.57x10-⁴ in standered form ?

Answer 1

Kaleerain5,

In order to get your answer you must remember that if the exponent is negative move to the left and if the exponent is positive you have to move to the right.

• 
  `8.57 * 10^(-4)`
• The exponent is negative so move to the left:
• 
  `8. = .8 = .08 = .008 = .0008`
• 
  `= .000857`

Therefore your answer is ".000857."

Hope this helps!
