evaluate if possible

1. square root -121

A not a real number

2. 3cube-8/27
would this be
3cube -2/3

number 1 is correct i've had that one in my homeworks previously.

number two i am not sure how it would actually look

3^3+ (-8)/(27)= If so to reduce it I have to agree with your answer.

the square root of 121 is 11 ..
11 * 11 = 121

unless you mean NEGATIVE 121?

what is the remainder when (2x3 - 3x2 - 10x + 15) (x + 2)

To evaluate the expression, we need to follow the specific rules and order of operations.

1. Evaluating the square root of -121:
The square root of a negative number is not a real number, as it involves imaginary numbers. In this case, the square root of -121 is not possible.

2. Evaluating 3^3 - 8/27:
First, simplify the exponent: 3^3 = 3*3*3 = 27.
Now, substitute the value back into the expression:
27 - 8/27

To simplify further, you can find a common denominator for the fraction:
27 - 8/27 = (27 * 27)/27 - 8/27 = (729 - 8)/27 = 721/27.

Therefore, the simplified form is 721/27.
