Answer:
0.1296
Step-by-step explanation:
(3÷5)^18 ÷ (3÷5)^16
Eighteen and sixteen will get canceled
(ie.when we write (3÷5) eighteen times divided by (3÷5) sixteen times we can cancel them.)
remaining there will be two (3÷5) at the numerator
so we get
a÷b=(3÷5)^2
a÷b=(0.6)^2
a÷b=0.36
value of (a÷b)^2=(0.36)^2
=0.1296
