2.25 x 10^-17. Because it's negative you move the decimal to the left. So 2.5 x 10^-8 is .000000025 and 9 x 10^-10 is .0000000009.
Answer:
A. x=2
b. x=28/3 and in decimal it is x=9.3 and in fraction it is
x= 9 1/3
c. x=20
d. x=20/11 in decamal x=1.81 in fraction it is x=1 9/11

n(A) = 26
Solution:
Let us first define the cardinal number of the set.
Cardinal number of the set:
The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A).
Given set: A = {a, b, c, .... z}
We know that, there are 26 elements in the alphabet "a to z".
Number of elements in the set A = 26
Hence n(A) = 26.
