Exponents

In my math class we have been asked to write a post about exponents.

If you have a problem such as 2^2 you would multiply 2*2 to get 4. Whatever the number of the exponent is, is how many times you will multiply the base by itself.

Example: 3^3= 3*3*3= 27 

If you get a problem like (4^2 7^2)3 you would multiply 2*3 to get 4^6. You would do the same for the next number to get 7^6. You would take 4^6 and multiply 7^6 to get 4^6*7^6.

Every time a number is to the 0 power the answer is always 1.

Example: 4^0= 1  -9^0= 1

Finding the Square Root of 59

First you have to find the closest squared numbers which are 49 and 64. The square root of 49 is 7 and the square root of 64 is 8 so the square root is some number after 7 and before 8. The number 7.5 squared is 56.25 so that narrows it down to the square root of 59 being in between 7.6 and 7.9. If you square 7.6 you get 57.76 so that narrows it down even more to its in between 7.7 and 7.9. You can probably guess that 7.9 is to much. If you squared 7.8 you would get 60.84 which is to much so what you do it square 7.7 which is 59.29. 59.29 isn’t exactly 59 but if you rounded it would be the closest. That’s how you find a square root.
