Question

i will mark u as brainliest pls answer this 18th and 23rd q

Answer 1

when n(A)=n
n(B)=m
so,

n(A×B)=n(A)×n(B)

= m×n
= mn

hp!

Answer 2

18th) (a1) = a as a 1×1 = 1 as in the exponent law. So a is common and power 1 is multiplied. To the 2nd power that is also 1 according to exponent law we multiply the 2 powers and it is 1 so we write it as a not as a1.

23) as n is common in the both factors and m is a new exponent so we take the common and the new exponent together and apply their powers to it. We see that the no of elements are 3 but n is common so there are 2. So A to the power mn × b to the power of n. There are 2 powers so they are m and n.
