ACT Practice, Scientific Notation, and Significant Figures
No Journal Today, ACT Practice instead! If you would like a copy of the ACT practice question that we did, see Mrs. Stant.
Scientific Notation and Significant Figures
SCIENTIFIC NOTATION:
To put a number into scientific notation, move the decimal until it is after the first non zero number. Write the new number x 10 (exponent). The exponent is determined by how many times you moved the decimal.
General Rule: If the final number is 1 or larger, the exponent will be positive. If the final number is smaller than one, the exponent will be negative.
Use page 37 in your book and the practice worksheet below to practice using Scientific Notation.
