Answer:
If you mean |x| and |-x| yes they are equal.
Step-by-step explanation:
Brackets do not exactly specify the meaning of absolute value.
On most keyboards, above the enter button on the main keyboard part (not the keypad one) there is a back slash symbol \ and if you hold shift, there might be another symbol | which more accurately represents absolute value,
If you aren't talking about the absolute value, then no.

Ooh is theis unions I did it but
Holigina, this is the solution:
Let's recall that √x = x ^(1/2)
Therefore,
√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)
The correct answer is C. 1
Answer:
+4.245
Step-by-step explanation:
Before you can find the square root of x^2, you have to EVALUATE
64+49-2(8)(7)cos32, and THEN take the square root of the result:
64+49-2(8)(7)cos32 = 64 + 49 - 112(0.848) = 113 - 94.981 = 18.019
Then x^2 = 18.019.
Find the square root of 18.019: It is +4.245. A negative result here would make no sense.
