What is scientific notation?

• Easy way to write numbers that are confusing

• Way to represent small numbers only

• A way to express very large and very small numbers

• Exponents and multipliers.

• True

• False

• The exponent tells me to move the decimal 5 places to the left.

• In standard form, the answer is less than 1

• The multiplier is too high.

• Answer in standarrd form: 0.0000367

• 155,000,000 kilometers
