Maths alevel index notationWatch
3/(e ^ 5) * 2/(root(3, e))
However could you help with this one
3 * (1/f^7/2))
3 " f^(-7/2))
That was pretty much what you described in the preceding posts, but your notation went wrong.
Then it's a case of doing something similar and dividing that expression by f^5. Note, using index notation, you could combine fs then negate the power (divide).
