Evaluate the numerical expression8×{[(7+4)×2]-[(11-7)×4]}

alina1380 [7]

Answer:

We have:

7 + 4 = 11;

11 - 7 = 4;

11 x 2 = 22;

4 x 4 = 16;

22 - 16 = 6;

Finally, 8 x 6 = 48;

Look at the following expression. Are there any values of x for which the expression is not defined under the set of real number

almond37 [142]

The expression $\frac{4}{\sqrt{x+2} }$ is not defined at x= -2 & for all values of x less than -2 .

<u>Step-by-step explanation:</u>

We have , a given expression as $\frac{4}{\sqrt{x+2} }$ : Basically we need to find domain for this function and see for which values of x the above function is undefined . Domain of a function is the set of values of x for which the function is defined . We have a rational expression, $\frac{4}{\sqrt{x+2} }$ it's a fractional function which means denominator can be 0 . Denominator = $\sqrt{x+2}$ $\neq 0$

⇒ $\sqrt{x+2}$ $\neq 0$

⇒ $x+2\neq 0$

⇒ $x \neq -2$

So , $x \neq -2$ . Also , Denominator is a square root expression so it can't be negative inside root ∴ $x+2 > 0$ ⇒ $x> -2$ i.e. x must be greater than -2.
