Mathematics

Answer:

k = -1/240

Step-by-step explanation:

to evaluate the value of k in the expression 1/3k+80=1/2k+120

we have

1/3k+80=1/2k+120

collect the like terms for easy evaluation

1/3k - 1/2k = 120 -80

1/3k - 1/2k = 40

find the lcm

2 - 3/6k = 40

-1/ 6k = 40

cross multiply

6k  x  40  = -1

240k = -1

divide both sides by 240

240k/240 = -1/ 240

k = -1/240

therefore the value of k in the expression 1/3k+80=1/2k+120 is equals to -1/240

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} }
