64x2.40 = 153.6
64x1.90 = 121.6
add 153.6 to 121.6
275.2
Number 16- 216
number 17- 180
number 18- 252
if a is related to b by some property, and b is related to c by the same property, then a is related to c by that property (Brainliest Answer Will be appreciated:D)
Answer:
1. If you're taking square roots, the number must be a perfect square to give a rational root.
64 = 8^2, so √64 = 8 is rational
Similarly, since
64 = 4^3, ∛64 = 4 is rational.
For small numbers, it's easy to check for possible roots, as there aren't that many candidates. In general, it's much more difficult.
2.
