Power of two - Wikipedia
WEBA power of two is a number of the form 2n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent . Powers of two with non-negative exponents are integers: 20 = …

WEBso 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Some more examples: Example: 53 = 5 × 5 × 5 = 125. In words: 5 3 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed". Example: 24 = 2 × 2 × 2 × 2 = 16.

WEB2 to the power of 1=2 Now when you look at these numbers, you should notice a pattern. 8/2=4, and 4/2=2. Now 2 divided by 2 would give us the answer to 2 to the power of 0, which is equal to 1.
Exponentiation - Wikipedia
WEBIn mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as b n, where b is the base and n is the power; this is pronounced as "b (raised) to the (power of) n ".
Laws of Exponents - Math is Fun
WEBExponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared" Try it yourself: So an Exponent saves us writing out lots of multiplies! Example: a7.

WEBso the first two 5 is 25(5x5=25) now we have 25 x 5 25 x 5 = (20 + 5) x 5 (20 x 5) + (5x5) 100 + 25 125 Another example: 4^2 = ? since "^2" says the power is rise to 2 that means we take the left number(4) and multiple it by itself 2 times 4 x 4 = 4^2 Now what is 4 x 4? 16 16 = 4^2 As you see the equation tells us that 4^2 is in fact 16
2.7: The Power Rules for Exponents - Mathematics LibreTexts
WEBThe Power Rule for Powers. The following examples suggest a rule for raising a power to a power: (a2)3 = a2 ⋅ a2 ⋅ a2. Using the product rule we get: (a2)3 = a2 + 2 + 2. (a2)3 = a3 ⋅ 2. (a2)3 = a6. (x9)4 = x9 ⋅ x9 ⋅ x9 ⋅ x9. (x9)4 = x9 + 9 + 9 + 9.
