Question

Simplify
4a x 6a
8a?

Answer 1

Simply multiply across.

since they both have the same base(a),add the powers ie.(1+1)=2.

Hence 4a×6a=24a²

Answer 2

`=24a^2`

Explanation:

`4a\cdot \:6a=24a^2\\\mathrm{Multiply\:the\:numbers:}\:4\cdot \:6=24\\=24aa\\\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^(b+c)\\aa=\:a^(1+1)\\=24a^(1+1)\\=24a^2`
