Question

Which real value of m makes the expression undefined

M^8+1/4m^2

Answer 1

m = 0

Explanation:

The denominator of the rational expression cannot be zero as this would make the rational expression undefined. Equating the denominator to zero and solving gives the value that m cannot be.

4m² = 0 ⇒ m² = 0 ⇒ m = 0 ← excluded value
