$a {}^{4} - a {}^{2} b {}^{2} + b {}^{4} \div 4$

Answer 1

Answer:

=4a3b10

Explanation:

In Algebra it is easier if you write a division as a fraction:

(2a2b3)44a5b2 ←remove the bracket

Law of indices: (xmyn)p=xmpynp
Power to a power - multiply the indices.

(2a2b3)44a5b2=24a8b124a5b2

=16a8b124a5b2 ← simplify the numbers

=4a8b12a5b2 ← subtract the indices

=4a3b10
