Question

125 в степени 2/3- 64 в степени 1/3

Answer 1

125 = 5³ ; 64 = 4³ ;

(5³)^2/3 - (4³)^1/3 = 5² - 4 = 25 - 4 = 21

Answer 2

To calculate this expression, let's first simplify the exponents:

125^(2/3) = (5^3)^(2/3) = 5^(3 * 2/3) = 5^2 = 25 64^(1/3) = (4^3)^(1/3) = 4^(3 * 1/3) = 4^1 = 4

Now we can substitute these values back into the expression:

125^(2/3) - 64^(1/3) = 25 - 4 = 21

So, 125^(2/3) - 64^(1/3) equals 21.
