*What is 13 to the 2nd Power? also written as 13^2
First: express the term without the exponent > when a number is squared it means multiply the number by itself (twice)...
(13)(13)
Sec: multiply the terms...
= 169

13 to the 2nd power is 169. It's the square of it so 13*13=169. If it was 13 to the 3rd power it would be 13*13*13.

13 times 13 equals 169, because 13 to the 2nd power is 13 times 13.
For example, if you had 2 to the 6th power, then you would do:
2 x 2 x 2 x 2 x 2 x 2 (which equals 64)
You just multiply the number by itself how many times the power says it to...
Try these:
1.) 0 to the power of 135,264,421,523,631. XD Sooo easy.
2.) 3 to the power of 4: 3 x 3 x 3 x 3= ?
3.) 8 to the power of 2: 8 x 8= ?
4.) 5 to the power of 3: 5 x 5 x 5= ?
5.) 10 to the power of 7: 10 x 10 x 10 x 10 x 10 x 10 x 10=?
*Hint for #5: The number of the power of tens is how many zeros you have... For example...
10 to the power of 2: 100 (2 zeros!)
10 to the power of 3: 1000 (three zeros!)
Answers:
1.) 0! Always zero!
2.) 3 x 3 x 3 x 3 simplifies to 9 x 9, which is 81!
3.) 64
4.) 125... Try to memorize this one because it's one of the most oftenly used exponential terms in equations... Trust me, It'll be easier on you if you remember this one... I know... XP
5.) 10,000,000

the second power is 13 times 13 (169), whatever the power is you multiply it, lets say it was 5 to the 5th power, it would be 5 * 5= 25 ,25 * 5 =125
125 * 5 = 625, and for the fifth , 625 * 5 = 1325.
on your scientific calculator there should be a x with a exponet y (exponet is a power) you take your number (13) and you press the button and you type in the power, and you get your answer. i hope that helped!!!
your answer to the question : 13 to the second power is 169

A number to the second power means to take the base (big number) times itself (i.e., 13 x 13).
A number raised to the third power means to use it as a factor 3 times (i.e., 13 x 13 x 13). As so on...

169. all you have to do is multiply 13 by itself. when ever you have powers, its just multiplying that number by however many times the power says. for instance 2 to the 3rd power is simply
2*2*2
2*2=4 then
4*2=8
I hope u understand my explanation
