00:00:00.000 --> 00:00:00.540


00:00:00.540 --> 00:00:03.730
Tumeambiwa tutafute kipeuo cha pili cha 100.

00:00:03.730 --> 00:00:05.130
Ngoja niichore hii alama kubwa hapa chini ionekane vizuri.

00:00:05.130 --> 00:00:09.060
Kwa hiyo kipeuo cha pili ni hii alama kubwa inayoonekana hapa

00:00:09.060 --> 00:00:11.880
Kipeuo cha pili cha 100.

00:00:11.880 --> 00:00:13.650
Ukiiona kama hii, ina maana

00:00:13.650 --> 00:00:15.120
kipeuo cha pili cha namba chanya.

00:00:15.120 --> 00:00:16.850
Kama ni mzoefu wa namba hasi, unafahamu

00:00:16.850 --> 00:00:19.490
pia kuna kipeuo cha pili cha namba hasi, lakini

00:00:19.490 --> 00:00:22.700
ukiona hii alama, ina maana ni kipeuo cha pili cha namba chanya.

00:00:22.700 --> 00:00:24.570
Hebu sasa tufanye hili swali.

00:00:24.570 --> 00:00:28.090
Tumeambiwa tutafute namba chanya,

00:00:28.090 --> 00:00:34.350
ambayo tukiizidisha kwa yenyewe tunapata 100.

00:00:34.350 --> 00:00:37.700
Je ni namba gani ambayo nikiizidisha kwa yenyewe ninapata 100?

00:00:37.700 --> 00:00:40.220
Hebu tuone, kama nikiizidisha 9 kwa yenyewe

00:00:40.220 --> 00:00:41.580
nitapata 81.

00:00:41.580 --> 00:00:44.280
kama nikiizidisha 10 kwa yenyewe, napata 100.

00:00:44.280 --> 00:00:46.800
Kwa hiyo, hii ni sawa na --ngoja niandike hapa

00:00:46.800 --> 00:00:48.740
Kawaida unaweza kuiruka hii hatua.

00:00:48.740 --> 00:00:51.470
Lakini unaweza kuiandika kama kipeuo cha pili cha --na

00:00:51.470 --> 00:00:56.610
badala ya 100, 100 ni sawa na 10 mara 10.

00:00:56.610 --> 00:00:58.960
Sasa umefahamu, kiepuo cha pili cha namba

00:00:58.960 --> 00:01:00.890
ukiizidisha kwa yenyewe itakuwa namba fulani

00:01:00.890 --> 00:01:03.240
Hii ni sawa na 10.

00:01:03.240 --> 00:01:06.720
Kwa hiyo kipeuo cha pili cha 100 ni 10.

00:01:06.720 --> 00:01:09.330
Au ungeweza kuiandika,

00:01:09.330 --> 00:01:16.520
10 ikizidishwa kwa yenyewe, ambayo ni sawa na 10 mara 10,

00:01:16.520 --> 00:01:20.000
ni sawa na 100.

00:01:20.000 --> 00:01:20.734
