Step-by-step explanation:
By Law of Indices, a^m * a^n = a^(m+n).
Therefore 8³ * 8⁵ = 8^(3+5) = 8⁸.
The left side of the equal sign is exactly the same as the right side, so it has infinitely many solutions.
Answer:
x=24cm
y=20,78cm
Step-by-step explanation:
sen(30)=
-> x*sen(30)=12 -> x=
= 24cm
cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm
