The first non-zero digit is 3. So, we move the decimal point to be right after the 3. This gives us the number 3.5. This value satisfies the rule for the coefficient, as it is between 1 and 10.<\/li>\n\n\n\n<li><strong>Find the exponent (b):<\/strong>\u00a0Now, we count how many places we moved the decimal point.Original position: 0.0000035<br>New position: 3.5To get from the original number to 3.5, we moved the decimal point 6 places to the right.<\/li>\n\n\n\n<li><strong>Determine the sign of the exponent:<\/strong>\u00a0The direction you move the decimal determines the sign of the exponent.<ul><li>If the original number is small (less than 1), the exponent will be negative.<\/li><li>If the original number is large (10 or greater), the exponent will be positive.<\/li><\/ul>Since 0.0000035 is a very small number (much less than 1), the exponent must be negative. Because we moved the decimal 6 places, the exponent is -6.<\/li>\n\n\n\n<li><strong>Combine the parts:<\/strong>\u00a0Finally, we put the coefficient and the exponent together in the proper format.<\/li>\n<\/ol>\n\n\n\n<p>The coefficient &#8216;a&#8217; is 3.5, and the exponent &#8216;b&#8217; is -6.
