you just do this x^5 :)
5 x 5 x 5
5^3 = 5 x 5 x 5
5 x 5 x 5 x 5 = 625
2 x 2 x 2 x 2 x 5 x 5 x 5
(2 x 5)2
3 x 3 x 3 x 3 x 3
3 x 3 x 3 x 3 x 3 = 243
604,100
Three and four tenths multiplied by ten to the fifth power
3^(5) = 3 x 3 x 3 x 3 x 3 = 243 The word 'exponent' can also be shown as ' index number' or 'power'.
The normal way to write this is: x3 (meaning x cubed / x to the third power).
