Writing Large Numbers in Scientific Notation Move the decimal to the right two place values. 2 6 x 10 = 600
Remember! The exponent is the same as the number of zeros. 2 6 x 10 = 600
What is the Standard Number? 4 9. 2 x 10 = 92, 000
What is the Standard Number? Move the decimal to the left three place values. -3 8. 24 x 10 = 0. 00824
What is the Standard Number? -2 7 x 10 = 0. 07
What is the Standard Number? 2 7 x 10 = 700
What is the Standard Number? 3 8. 24 x 10 = 8, 240
