What does it mean to raise a number to an exponent?
To raise a number to an exponent means to multiply it by itself as many times as the specified exponent. For example: 23 or "two to the power of three" is the same as 2 × 2 × 2 35 or "three to the power of five" is the same as 3 × 3 × 3 × 3 × 3 y2 or "y to the power of two" (or "y squared") means y × y

What is the power of 5 about?
In math, there are many terms that have to do with multiplying a number times itself. An example is 3 x 3 =9 Two identical numbers multiplied together gives an answer "To the power of 2". '9' is "3 to the power of 2" because 3x3=9. (2 3s . . . power of 2) Multiply 3 identical numbers, say, 5x5x5 = 25. So '25' is "5 to the power of 3". Multiply 4 identical numbers, say 1x1x1x1. So '1' is "1 to the power of 4". Or, 2x2x2x2 = 16, so '16' is "2 to the power of I bet you see where this is going: Ohhh, how about 10x10x10x10x10 = 100,000, so '100,000' is "10 to the power of 5".

How could you find the the number with the prime factorization of 2 to the second power times 3 to the second power?
Multiply. 2 x 2 x 3 x 3 = 36
What is 343 to the power of two thirds?
343 is 7 to the power of 3 ( 7 x 7 x 7 = 343) To find 7 to the 3 power to the 2/3 power you multiply the exponents and raise 7 to that power: 3 x 2/3 = 2 7^2 = 49

How do you work out 2 to the power of 6?
The power just means how many times you multiply 2 by itself. You would work it out by doing 2 x 2 x 2 x 2 x 2 x 2 = 64
What is2 to the 3 power?
2 to the power of 3 is equivalent to 2 x 2 x 2. 2 x 2 = 4 Then multiply the answer (4) by 2 again, for 8. 2 x 2 x 2 = 8

What does raising a number to the second power mean?
multiply the number by itselfRaising a number to the second power means you are squaring the number, multiplying it by itself. 2 squared= 2*2=43 squared=3*3=9
1 times 2 times 3 third power times 1?
27. 1 times 2 is just 2. 3 to the third power is 3 times 3 which is 9, times 3, which is 27. If you multiply that by 1 again, it's STILL 27.
When adding a number with exponents do you add or multiply the exponents?
NEITHER! Look at 4+8 which you know is 12 4 is 2^2 and 8 is 2^3 2^2+2^3=12 but no power of 2 is equal to 12? So the answer is NEITHER. When you multiply numbers, you add the exponents and when you raise and exponent to a power, you multiply exponents. In the example i gave, you could factor out the smallest power and you have 2^2(1+2)=2^2x3=4x3=12 That is how you do this type of problem. Either raise the numbers to their powers and add them, or factor and add.
