Question

(b) Find the LCM and HCF of the following algebraic expressions:

(i) x2, x3, x5

Answer 1

Answer:

Expressions:

==> x² , x³ , x^5

x² = x²

x³ = x² × x

x^5 = x² × x² × x

HCF = product of common factors with lowest power

==> HCF = x²

LCM = product of prime factors with highest power

==> LCM = x² × x² × x

==> LCM = x^5
