1. Calculate the H. C. F of a 2 b 5 and a 3 b 3.

Step-by-step explanation:

Problem is HCF:

Of;

a²b⁵ and a³b³

The highest common factor, HCF is used to factor expressions in order to simplify them.

H. C. F is a factor that is common to both expressions.

here we have

a²b⁵ and a³b³

a²b⁵ = a x a x b x b x b x b x b

a³b³ = a x a x a x b x b x b

In both expressions, for a:

a x a and b x b x b x b x b

a x a x a and b x b x b

common factors are a and b

both entities contains a and b

Highest common factor H. CF;

a² and b³

this makes a²b³

a²b³ is common to both of them and it is the highest term that can be factored from the the two.
