Question

When adding monomials, both the coefficients and exponents are added. true or false

Answer 1

false if the exponents are equal then the coeffiecients are added and the exponents remain the same if the exponents are different the two cannot be added

for example
\[2x ^{2} + 3x ^{2} = 5x ^{2}\]

but
\[2x ^{2}+2x =2x ^{2}+2x\] diff powers

also
\[2x ^{2}+2y^{2} =2x ^{2}+2y^{2}\] diff variables
