Simplify: squareroot 64r^8 8r2 8r4 32r2 32r4

  8r^4

Step-by-step explanation:

√(64r^8) = √((8r^4)^2) = 8r^4

_____

You can make use of either or both of these rules of exponents:

  (a^b)^c = a^(b·c) . . . . . used above

Using the second rule, you can write the expression as ...

step-by-step explanation:

the shape,the size and the distance

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
