1) the square root of 64=8

2) The square root of a^4=a^2

3) b^5=b√b

so the first amount simplifies to 8a²b²√b

4) ∛64=4, as 4×4×4=64

5) ∛a^5=a√a²

6)∛b^4=b√b

so...the second amount is equal to 4ab∛a²b

The last one should be correct

Hope this helped :)

How to convert this equation to y=mx+b form:<br> y+2x=y-2
wlad13 [49]
Y = mx + b is in the form of slope-intercept.
From the equation given, y + 2x = y - 2, we can convert it in the format of the slope intercept form and it depends we can came up to that form.

y + 2x = y -2
y - y = -2x - 2
0 = 2x + 2
x = -1

Unfortunately, the form y = mx + b is impossible to achieve.

Answer:

1) The value of c is given by

c=4

2) The value of k is given by

k=-4150

Step-by-step explanation:

Given that function g is defined by g(x)=cx-3 , where c is a constant.

To find c:

Also given that value of g(x) at x=0.5 is equal to -1

ie., g(0.5)=-1

At x=0.5

g(0.5)=c(0.5)-3=-1

(0.5)c-3=-1

(0.5)c=-1+3

(0.5)c=2

c=\frac{2}{0.5}

c=\frac{2}{\tfrac{1}{2}}=2\times \frac{2}{1}

Therefore c=4

2) Given that function h is defined by h(x)=\frac{20x-k}{x+50} , where k is a constant.

To find k:

Also given that value of h(x) at x=20 is equal to 65

ie., h(20)=65

At x=20

h(20)=\frac{20(20)-k}{20+50}=65

400-k=65(70)

-k=4550-400

-k=4150

Therefore k=-4150
