On my key-board what key will i use to type (x to the fourth power? ) and also what keys do i use to set up a fraction?

So when clicking the answer button, when you can type, look at the bottom left,

you can see 4 symbols: B, pi, omega, and a paperclip
B is bold
pi is insert equation
omega is symbols
paperclip is attachment

you click on the pi symbol
then experiment

if you don't want nice script
use the ^ sign for x^4 (it is above teh 6 key for me, press shift)

55. i don’t no. but zhongshan

Ithink it’s d as the answer.
