A) 4x10+5-1+300-7
B) 10x10+100
C) 500x10+10
D) 1.5^3

Answer 1

The real numbers that are equal to their cubes are 0 and 1.

Step-by-step explanation:

The real numbers that are equal to their cubes are 0 and 1. Any number raised to the power of 3 is called cubing. For example, 2³ = 2 × 2 × 2 = 8.

Looking at the options given, we can see that option D, 1.5³, equals 3.375, which is not equal to 1. Therefore, the correct answer is not provided in the options given.
