Answer:

x^\frac{21}{5}

Step-by-step explanation:

We are given an expression and we have to transform it into an expression with exponent.

5th root of x can be written as x^\frac{1}{5}

(\sqrt[5]{x^7})^3\\\\((x^7)^\frac{1}{5} )^3


The powers outside will be multiplied as: (x^a)^b = x^{ab}

(x^\frac{7}{5} )^3\\x^\frac{7*3}{5}\\x^\frac{21}{5}


where the exponent is \frac{21}{5} and it is a rational number by definition of rational numbers

What is the slope of the line that passes through (8,4) and (6,7)?
bija089 [108]
slope=\frac{y_2-y_1}{x_2-x_1}\\\\ 
(x_1,y_1)=(8,4)\\ 
(x_2,y_2)=(6,7)\\\\
 slope=\frac{7-4}{6-8}=\frac{3}{-2}=-\frac{3}{2}\\\\
Slope\ is\ equal\ to\ -\frac{3}{2}.

Decrease 700kg by 25% <br> (With working out)
Natali5045456 [20]

Answer: 525kg

Step-by-step explanation:

To decrease 700kg by 25% implies

700 - 25% of 700kg

25% of 700 = 25/100 × 700kg

0.25 x 700

= 175

Therefore, to decrease 700kg by 25%, since 25% is 175kg, we subtract 175kg from 700kg

700kg - 125kg

= 525kg

PLEASE HELP ME WITH THESE FOUR QUESTIONS TYSMMM!!! THANK YOU
Dima020 [189]

Answer:

107^\circ, 133^\circ, 20^\circ, \text{and}, 23^\circ

Step-by-step explanation:

9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:

x+73^\circ=180^\circ

x=107^\circ

10. For the lines  'm' and 'n' to be parallel the alternate exterior angles should be equal that is:

147^\circ=x+14^\circ

x=147^\circ-14^\circ

x=133^\circ

11. For the lines  'm' and 'n' to be parallel alternate angles should be equal that is:

180^\circ-3x=2x+20^\circ

Solving for 'x' we get:

180^\circ-20^\circ=3x+2x

5x=160^\circ

x=32^\circ

12. For the lines  'm' and 'n' to be parallel corresponding angles should be equal that is:

(7x-11)^\circ=(4x+58)^\circ

7x-4x=58^\circ+11^\circ

3x=69^\circ

x=\frac{69}{3}=23^\circ

Answer:

I think the working is actually unnecessary because of (x-c)=0 and if x is 5 (5-c)=0 c would be 5
