The exponent button is shown as y^x (Y is your number raised to X, the exponent number). The negative exponent tells us to re-write the expression by taking the reciprocal of the base and then changing the sign of the exponent. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Example. Enter a number, press this key and the display will show the value of e raised to the exponent you entered. Enter 10, press the exponent key, then press 5 and enter. Completely clears the calculator. In their simplest form, exponents stand for repeated multiplication. For example, if you see 33{\displaystyle 3^{3}}, you know that you are going to multiply 3{\displaystyle 3} by itself 3{\displaystyle 3} times, which comes out to be 27{\displaystyle 27}. Learn more... Exponents tell you how many times any given number is multiplied by itself. This rules states that any number raised to a negative number can be calculated by the reciprocal of that number raised to the absolute value of the negative number. Since taking the log() of negative numbers causes calculation errors they are not allowed. The calculator will display the value of the number raised to the negative exponent. It’s a way to change division problems into multiplication problems.

Example: Instead of […] This is found in most word processing and Internet programs that allow the typist to put in different and special characters. Negative exponents can be written as 2−2,(2−2)1,1(22),{\displaystyle 2^{-2},{\frac {(2^{-2})}{1}},{\frac {1}{(2^{2})}},} or 12x2{\displaystyle {\frac {1}{2x2}}}. This process is known as the negative exponent rule. I've been using the ^ key for exponents. Quote of the day ... Show me Another Quote! In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared" . a n × a m = a (n+m) EX: 2 2 × 2 4 = 4 × 16 = 64 2 2 × 2 4 = 2 (2 + 4) = 2 6 = 64 When an exponent is negative, the negative sign is removed by reciprocating the base and raising it to the positive exponent. Because the exponent is negative, the subtraction will cancel out the second negative and make the exponent positive. The problems in this lesson involve zero and negative exponents. In 8 2 the "2" says to use 8 twice in a multiplication, so 8 2 = 8 × 8 = 64.
