It expresses a number in the form <em>a \u00d7 10\u207f<\/em>, where <em>a<\/em> is a number between 1 and 10, and <em>n<\/em> is an integer that tells us how many places to move the decimal point.<\/p>\n\n\n\n<p>To write 0.00003 in scientific notation, we first identify the significant digits: here, that\u2019s 3. We then determine how many places we must move the decimal point to convert 0.00003 into 3. The decimal needs to shift <strong>five places to the right<\/strong>. Since we are making a small number larger, the exponent of ten must be <strong>negative<\/strong>, indicating a number much less than 1.<\/p>\n\n\n\n<p>So we write:<\/p>\n\n\n\n<p>0.00003 = 3 \u00d7 10\u207b\u2075<\/p>\n\n\n\n<p>The negative exponent tells us that the decimal point in 3 \u00d7 10\u207b\u2075 has moved five places to the left to reach 0.00003.<\/p>\n\n\n\n<p>To confirm:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>10\u207b\u00b9 = 0.1<\/li>\n\n\n\n<li>10\u207b\u00b2 = 0.01<\/li>\n\n\n\n<li>10\u207b\u00b3 = 0.001<\/li>\n\n\n\n<li>10\u207b\u2074 = 0.0001<\/li>\n\n\n\n<li>10\u207b\u2075 = 0.00001<\/li>\n<\/ul>\n\n\n\n<p>Then: 3 \u00d7 0.00001 = 0.00003<\/p>\n\n\n\n<p>That verifies the conversion is accurate.<\/p>\n\n\n\n<p>The other options are incorrect:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3 \u00d7 10\u00b2 = 300<\/li>\n\n\n\n<li>3 \u00d7 10\u2075 = 300000<\/li>\n<\/ul>\n\n\n\n<p>These represent numbers far larger than the width of a skin cell.<\/p>\n\n\n\n<p>Scientific notation is commonly used in science and engineering where extremely small or large values are frequent. It makes reading, comparing, and calculating these quantities much more manageable.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-608.jpeg\" alt=\"\" class=\"wp-image-34964\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-608.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-608-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-608-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Please give me the correct answer.
