Why won't my Nextbook tablet model NX785QC8G-R read my 64 gb micro sd card?

[AC Question]

So, I recently paid $30 to buy a 64 gb micro SD card and my tablet won't read the card AT ALL! I was told that this card would expand my memory, but the tablet won't read it. The tablet itself has 8 gb, so naturally I wanted more memory. Please help me figure out what I'm doing wrong.
