Question

If a = −2, b = −3, c = 2, x = 2.1, y = 3,

and z = −4.2.




||y−2z||−3

Answer 1

The expression ||y-2z||-3 represents the absolute value of the difference between y and 2z raised to the power of -3. Substituting the given values, the expression evaluates to 11.4^-3.

Step-by-step explanation:

The expression you provided, ||y-2z||-3, represents the absolute value of the difference between y and 2z raised to the power of -3.

Substituting the given values for y and z, the expression becomes ||3-2(-4.2)||-3. Simplifying further, we have ||3+8.4||-3, which is equal to ||11.4||-3.

The absolute value of 11.4 is 11.4, so the final value of the expression is 11.4^-3.
