Q9 of 108 Page 46

The HCF of expression 8a2b2c and 20ab3c2 is:

Let us write both the expressions in factorized form.

Let u(x) = 23 × a2× b2 × c


Let v(x) = 22 × 5 × a × b3 × c2


So by comparing u(x) and v(x), HCF = 4ab2c [Least power of variables and common terms]


So the correct answer is A [4ab2c].
