1 00:00:00,000 --> 00:00:00,690 2 00:00:00,690 --> 00:00:03,960 Find the value of 5 to the third power. 3 00:00:03,960 --> 00:00:05,019 Let me rewrite that. 4 00:00:05,019 --> 00:00:07,910 We have 5 to the third power. 5 00:00:07,910 --> 00:00:10,339 Now, it's important to remember, this does not 6 00:00:10,339 --> 00:00:12,629 mean 5 times 3. 7 00:00:12,630 --> 00:00:17,769 This means 5 times itself three times, so this is equal 8 00:00:17,769 --> 00:00:23,689 to 5 times 5 times 5. 9 00:00:23,690 --> 00:00:26,929 5 times 3, just as a bit of a refresher so you realize the 10 00:00:26,929 --> 00:00:31,679 difference, 5 times 3-- let me write it over here. 11 00:00:31,679 --> 00:00:41,369 5 times 3 is equal to 5 plus 5 plus 5. 12 00:00:41,369 --> 00:00:44,820 So when you multiply by 3, you're adding the number to 13 00:00:44,820 --> 00:00:46,689 itself three times. 14 00:00:46,689 --> 00:00:49,519 When you take it to the third power, you're multiplying the 15 00:00:49,520 --> 00:00:51,980 number by itself three times. 16 00:00:51,979 --> 00:00:55,719 So 5 times 3, you've seen that before, that's 15. 17 00:00:55,719 --> 00:01:00,649 But 5 to the third power, 5 times itself three times, is 18 00:01:00,649 --> 00:01:07,400 equal to-- well, 5 times 5 is 25, and then 25 times 5 is 19 00:01:07,400 --> 00:01:12,760 125, so this is equal to 125. 20 00:01:12,760 --> 00:01:14,270 And we're done! 21 00:01:14,269 --> 00:01:14,598
