11/d^3 × (–7/d^4)
= – 77/d^7

I Thank the Lord for the evening time - Neil Diamond Nights in White Satin - Moody Blues Brickfield Nights - the lads Days Are ok however the Nights Are Made for romance - the inns ineffective night on the Oasis - Maria Muldaur BQ: very almost something that would not suck works for me BQ2: i'm kinda keen on the early morning, till now the sunlight comes up

I am reading this as :-

11 (-7)
----------------
d³ d^4

-77
-----
d^7

(11/d^3)(-7/d^4)
= (11 * -7)/(d^3 * d^4)
= -77/d^7

(11/d^3)/(-7/d^4)=11d/-7
11/d^3)x(-7/d^4)=-77/d^7
