The sun is about 93 million miles from the earth. Express this distance in scientific notation. A) 0.93 x 10^8 B) 9.3 x 10^7 C) 9.3 x 10^6 D) 93 x 10^6

Answer:B.) 9.3 × 10^7Step-by-step explanation:The decimal point is to the right of the last zero, so move it to the left until you get in between the 9 and 3, so that there is only one digit to the left. That's 7 spaces, so your answer will be 9.3×10^7.Scientific notation will always be written as a number×10 raised to a power.The number will be between  1 and 10. In case you ever have a scenario when your decimal moves the other way, the exponent then would be negative. For now your exponent is positive.
