The exponent is 2 - from the SECOND power.
It is: 7^2 = 49
32
You multiply the exponents. For instance (23)3 = 29 : (54)1/2 = 52: (7-2)5 = 7-10
If you mean 7^2 then 2 is the exponent and it means 7*7 = 49
2 x 2 x 3 x 7 x 7 x 11 2 x 2 x 3 x 3 x 7 The GCF is 2 x 2 x 3 x 7
532 = 2 * 2 * 7 * 19 = 22 * 7 * 19
2^2 x 3^2 x 7
Factor both;Factors of 14 are 7 and 2Factors of 20 are 22 and 5.The highest exponent that appears for 2 is 2, the exponent for 5 is 1, and the highest exponent for 7 is 1.So we multiply.22 * 51 * 71 = 140
7-2 = 1/72 = 1/49
An exponent is a superscripted number or value (2x+3, 7, 4, -3, etc) that tells you how many times to multiply an item by itself. For example, 24 (2 with an exponent of 4) is 2 x 2 x 2 x 2, or 16.
However many variables there are is the exponent. 2x2x2x2x2x2x2 = 2^7 3x3x3 = 2^3 etc.
