    When powers of 10 are multiplied together, the powers are added together. For example, 102<\/sup> \u00d7 103<\/sup> = 102+3<\/sup> = 105<\/sup>. With this in mind, can you evaluate (4.506 \u00d7 104<\/sup>) \u00d7 (1.003 \u00d7 102<\/sup>) without entering scientific notation into your calculator?<\/p>\r\n\r\n<\/div><\/li>\r\n \t
