simplify M raised to the power 4 minus 1 divided by M raise to the power 2 minus 1

Answer 1

M power 4 - 1 can be written as M raised to power 2 whole square - 1 square So we get M power 2 square - 1 square  Now a square - b square =(a+b) (a-b) So, (m power 2  +1) (m power 2 - 1) Now m power 2 - 1 gets cancelled. So we get m power 2 +1
