A. 1
20
B. 1
40
C. 1
2
D. 1
4

Answer 1

I’m not sure how to read the expression as you typed it. Could you please rewrite it using ^ for exponents and parentheses for grouping? For example:

- sqrt(0.64) * (cuberoot(64))^2 * 3^(2-5)
or
- sqrt(0.64) * (cuberoot(64^-1))^2 * 3^(2-5*1)

Either of those (or another grouping) changes the result. If you post the expression in one of those formats I’ll compute it and match it to the choices. If you meant the cube root, you can write it as cuberoot(64) or 64^(1/3).
