Describe the process of rewriting the expression Please Help
Mazyrski [523]

Answer:

x^{\frac{21}{4} }

Step-by-step explanation:

Given expression is:

(\sqrt[8]{x^7} )^{6}

First we will use the rule:

\sqrt[n]{x} = x^{\frac{1}{n} }

So for the given expression:

\sqrt[8]{x^{7}}=(x^{7} )^{\frac{1}{8} }

We will use tha property of multiplication on powers:

=x^{7*\frac{1}{8} }

= x^{\frac{7}{8} }

Applying the outer exponent now

(x^{\frac{7}{8} })^6

= x^{\frac{7}{8}*6 } \\= x^{\frac{42}{8} }\\= x^{\frac{21}{4} }

a rectangle has an area of x2+8x+15 square meters and a width of x+3 what expression represents the length of the rectangle
anzhelika [568]

Answer:

1x + 5

Step-by-step explanation:

Since the area of a rectangle of width w and length l is A = l*w,

length = Area / Width.

Here,                             x^2 + 8x + 15

length of rectangle  = ----------------------

                                            x + 3

Use synthetic division to perform the above.  The coefficients of the quadratic are a = 1, b = 8 and c = 15, and the divisor is -3 (from (x + 3).

-3      /  1        8        15

                    -3        -15

        -------------------------

            1         5        0

Since the remainer is zero (0), -3 is a root and 1x + 5 is a factor of the quadratic.  This factor, representing the length of the rectangle, is 1x + 5.

Next time, kindly share the answer choices.  Thank you.
