So, for example, <math>3^4</math> is the same as <math>3 x 3 x 3 x 3</math>, which equals <math>81</math>.
<br><br>
This is spoken as “three to the fourth power” or “three to the fourth”. There are two exceptions to this: The power of two is generally called “squared” so <math>3^2</math> is “three squared”. The power of three is referred to as “cubed” so <math>3^3</math> is “three cubed”.
<br><br>
Exponents are especially useful when dealing with variables, such as <math>x^3</math>. There are a few rules in simplifying several variables raised to a power in one expression.
<br><br>
When two terms with the same base are multiplied, the exponents are added:
<math>(b^n)(b^m) = b^(n+m)</math>
<br><br>
When raising a power to a power, the exponents are multiplied with each other:
<math>(b^n)^m = b^(n*m)</math>
In other words, if the entire expression <math>b^n</math> is raised to the power of <math>^m</math>, the new power of b is the product of n multiplied by m.
<br><br>
Any number to the power of zero equals 1, as long as the base value itself is not 0.

Enter your problem into Tiger’s calculator and the step-by-step solution will help you understand how to raise a number or an expression to a power.
<br><br>
Tako je, na primer, <math>3^4</math> isto što i <math>3 x 3 x 3 x 3</math>, što je jednako <math>81</math>.
<br><br>
Ovo se govori kao „tri podignuto na četvrti eksponent“ ili „tri na četvrti”. Postoje dva izuzetka od toga: Eksponent dva se obično naziva „na kvadrat“, pa je <math>3^2</math> „na kvadrat“. Eksponent trojke naziva se „na treći“, tako da je <math>3^3</math> „na treći“.
<br><br>
Eksponenti su posebno korisni kada se radi o promenljivim, kao što je <math>x^3</math>. Postoji nekoliko pravila za pojednostavljivanje nekoliko promenljivih podignutih u stepen u jednom izrazu.
<br><br>
Kada se pomnože dva člana sa istom osnovom, dodaju se eksponenti:
<math>(b^n)(b^m) = b^(n+m)</math>
<br><br>
Pri podizanju eksponenta u stepen, eksponenti se međusobno množe:
<math>(b^n)^m = b^(n*m)</math>
Drugim rečima, ako se celokupan izraz
<math>b^n</math> podigne na stepen <math>^m</math>, nov eksponent b je proizvod n pomnožen sa m.
<br><br>
Bilo koji broj sa nulom jednak je 1, sve dok sama osnovna vrednost nije 0.

Unesi svoj problem u Tiger kalkulator i korak po korak rešenje će ti pomoći da razumeš kako podići broj ili izraz u stepen.
