8^2 = 64 The exponent is 2
The exponent is an unknown variable. It is a variable because it will change into a known number when we get further into the equation. Take this for example. 4x=8 - where x is the exponent. To work out the problem we simply move the 4 over the equal's sign. Since it is 4x, this means that it is 4 times x. Since we are moving the 4 over the equals sign, we have to change the multiplication, into a division. x=8/4 which equals 2. The x is a 2. To check, we we substitute the 2 with the x in the equation. 4x2=8, which is correct.

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
A power is a shortcut for repeated multiplication. The exponent tells you how often the factor must appear. For example, 84 = 8 x 8 x 8 x 8. Similarly, a multiplication is a repeated addition.
8 with an exponent of four
An exponent involve two numbers. For example: 8 to the power of 2 means 8 x 8 = 64. It can be expressed: 8^2 = 64, or 8² = 64
The reason you use 2 for the exponent when saying a number squared is because you are taking the number with the exponent of 2 and multiplying it by itself. 2^2 = 4 since 2 x 2 = 4. After squared is cubed for an exponent of 3, 2^3 = 8, since 2 x 2 x 2 = 8.

27 = 128 = (1 x 100) + (2 x 10) + (8 x 1)
2^8 = 216
When you take the square root of a variable raised to an exponent, you divide the exponent by two. For example the square root of x^4 is x^2, because x^2 x x^2 =x^4.
