R + 3 1/2 = -4 2/3
alexandr402 [8]

Answer:

R = -8 1/6

Step-by-step explanation:

We'll solve the given equation for R.

Subtract 3 1/2 from both sides of the equation, to isolate R:

           R +  3 1/2  -  3 1/2 = -4 2/3  - 3 1/2, or

            R = -4 2/3 - 3 1/2

The LCD here is 6, which is the product of 3 and 2.  Converting the fractions to denominator 6, we get:

              R = -4 4/6 - 3 3/6, or

               R = -7 - 7/6, or R = -7 - 1 1/6, or -8 1/6

belka [17]

Answer:

\sqrt[4]{ {x}^{3}  }

Step-by-step explanation:

\sqrt{x}  \times  \sqrt[4]{x} \\  =  {x}^{ \frac{1}{2} }  \times  {x}^{ \frac{1}{4} }  \\  =  {x}^{ \frac{1}{2}  +  \frac{1}{4} }  \\  =  {x}^{ \frac{3}{4} }  \\  =  \sqrt[4]{ {x}^{3} }
