There's no such thing as "the fifth square" of a number.To calculate any whole-number power of a number, write the number that many timesall on one line, then write the word "times" between them, get your pencil out, and getto work.The 5th power of a number 'N' is'N' times 'N' times 'N' times 'N' times 'N' .
One-fifth is 1/5 or 0.2

You write 32, where that two is the number of times you are multiplying 3 by itself (3 x 3 x 3 = 33) and it is to the upper right of the number. You say 32 as "three squared," 33 as "three cubed," and everything higher as you would if the power were a place in a race, so 345 is "three to the forty-fifth power."

If x is your variable, it would be 6x+7x. If x is negative, it would be 6(-x)+7(-x).
