Apha, Uyenza lula njani i-2 ukuya kumandla angalunganga wesi-3?
Uzenza njani ii-exponents ezingalunganga? I-exponent engalunganga ichazwa njenge inguqu ephindaphindayo yesiseko, ephakanyiselwe kumandla achasene namandla anikiweyo. Ngamagama alula, sibhala ukuphindaphindana kwenani kwaye emva koko silisombulule njenge-exponents ezivumayo. Umzekelo, (2/3)-2 inokubhalwa njenge (3/2)2.
Ukongeza Yintoni u-2 ukuya kweyesi-3 amandla enziwe lula? Impendulo: I-2 iphakanyiswe kwigunya lesithathu ilingana no-23 = 8. Ingcaciso: I-2 ukuya kumandla we-3 ingabhalwa njenge 23 = 2×2×2, njengoko u-2 uphindwaphindwa yedwa 3 amaxesha. Apha, u-2 ubizwa ngokuba "sisiseko" kwaye u-3 ubizwa ngokuba "yi-exponent" okanye "amandla."
Yintoni u-10 kumandla angalunganga ka-3? Impendulo: 10 kumandla ka-negative 3 ngu 0.001.
Ngaba i-negative kumandla ka-2 negative?
Impendulo: Inani elithabathayo kumandla we-2 soloko linani eli-positive. Masiqonde isisombululo. Ingcaciso: Xa sibala i-exponent yenani elithabathayo, ngoko umphumo uxhomekeke kumandla enani.
Ngubani u-2 kumbane ongekhoyo ku-2?
Yintoni u-10 kumandla angalunganga ka-2? Impendulo: Ixabiso le-10 kumandla we-negative 2 ngu 0.01.
Ngubani u-10 kumbane ongekhoyo ku-7?
Impendulo: 10 kumandla ka-negative 7 ulingana no 0.0000001.
Kwakhona Yintoni i-negetive ka-2? I-negative ka -2 ngu 2.
Kutheni kumandla ka-2 kungalunganga?
I-exponent engalunganga ithetha nje ukuba isiseko sikwicala elingalunganga lomgca weqhezu, ngoko kufuneka uguqule isiseko kwelinye icala. Umzekelo, “x-2” (libizwa ngokuba “ecks to minus two”) lithetha nje “x2, kodwa ngaphantsi, njengaku 1 x 2 frac{1}{x^2} x21”.
Ngaba uthabatha 1 ophindwe kabini ngokuchaseneyo? (-1)^2 = (-1) (-1) = 1. Isikwere salo naliphi na inani eli-negative lihlala li-positive!!! Ngaphandle kokuba uzama ukuthi-negative ka-1 ophindwe kabini ongu-(1)^2 kwaye ilingana no -1.
Yintoni u-5 kumandla ka-negative 2 njengeqhezu?
⇒ 5-2 = 1 / 52 = 1/(5 × 5) = 1/25 = 0.04. Jonga i-exponent calculator ukwenza ukubala kwakho kube lula.
Lithini inani ukuya kumandla othabatha u-2?
Izalathisi ezilandulayo zithetha ukuba endaweni yokuphinda-phinda inani elininzi lesiseko kunye, uyahlula. Umzekelo, 52=25 kodwa 5−2=152=125 . Ungasebenzisa imveliso yepropathi yamagunya ukubonisa oku.
Yintoni u-10 kumandla angalunganga ka-4? Impendulo: 10 kumandla ka-negative 4 ulingana no 0.0001.
Masiqonde isisombululo ngenyathelo.
Yintoni u-5 kumandla angalunganga ka-2? Impendulo: 5 kumandla ka-negative 2 ngu 0.04.
Ngubani u-10 kumbane ongekhoyo ku-1?
Amandla angalunganga
| igama | amandla | inani |
|---|---|---|
| Nye | 0 | 1 |
| yeshumi | -1 | 0.1 |
| ikhulu | -2 | 0.01 |
| iwaka | -3 | 0.001 |
Kuthetha ukuthini u-10 ukuya kumandla wesi-5? 10-5 == 0.00001.
Yintoni u-10 nge-exponent ka-2?
Impendulo: Ixabiso le-10 kumandla we-negative 2 ngu 0.01.
Yintoni u-3 ngamandla ka-3? Iitheyibhile ze-Exponent kunye neepateni
| Amandla ali-3 | Amandla ali-9 |
|---|---|
| 33 = 27 | 93 = 729 |
| 34 = 81 | 94 = 6561 |
| 35 = 243 | 95 = 59,049 |
| 36 = 729 | 96 = 531,441 |
Yintoni ethabatha u-2 kwi-exponent ka-4?
Inani elithabathayo kumandla alinganayo liyakuhlala lilungile. -2^4 yahlukile ku-(-2)^4. -2^4 ilingana nokuphinda-phinda 2^4 ngo -1. Ngoko kuya kuba njalo -16.
Leliphi inani elithabathayo kumandla ka-3?
Yintoni isikwere sika-3?
Yintoni ityhubhu ka-negative 5? Ingcambu ye-cube ye-5 ilingana ne-negative ye-cube ingcambu ye-5. Ngoko ke, ∛-5 = -(∛5) = -(1.71) = -1.71.
Yintoni kwi-negative 2 amandla?
I-exponent engalunganga ithetha loo nto isiseko sikwicala elingalunganga lomgca wamaqhezu, ngoko ke kufuneka ujike isiseko kwelinye icala. Umzekelo, “x-2” (libizwa ngokuba “ecks to minus two”) lithetha nje “x2, kodwa ngaphantsi, njengaku 1 x 2 frac{1}{x^2} x21”.
Usombulula njani kumandla we-negative 2?
