A deck as 52 cards and 4 kings
p(king) = 4/52 =1/13
[Getting l as in the letter “L” and not the letter “i” right?]
P(l) = 1/10
P(king and I) = 1/13 x 1/10 = 1/130
21/7.5 = 2.8
2.8 in fraction is 2 8/10
2 8/10 in lowest terms is 2 4/5
hope this helps
3 to fourth power=3^4
3 to ninth power =3^9
Now,
3 to fourth power times to the ninth power=3^4*3^9
the basis same so the powers will add:
3^(4+9)=3^13=1594323
