Answer:
1 and 3
Step-by-step explanation:
- (5^(1/3))^2 = 5^(2/3)
- (5^2)^(1/2) = 5^(2/2) = 5
- (5^2)^(1/3) = 5^(2/3)
- (5·3)^(1/2) = 5^(1/2)·3^(1/2)
- (5^(1/2))^3 = 5^(3/2)
- (5·2)^(1/3) = 5^(1/3)·2^(1/3)

- Completing the Square: b/2a
Step-by-step explanation:
<u>Step 1: Define expression</u>
x² + 8x - 5 = 15
<u>Step 2: Solve</u>
- Isolate <em>x</em> terms: x² + 8x = 20
- Complete the Square: (x² + 8x + 16) = 20 + 16
- Simplify: (x + 4)² = 36
Standard form is ax+by=c
First find the slope, (y2-y1)/(x2-x1)=(1--4)/(5-0)=5/5=1, so if we use the form:
y=mx+b we have
y=x+b, using either point, I'll use (5,1) we can solve for b
1=5+b
b=-4 so in slope intercept form we have:
y=x-4 Now we rearrange so that x and y are on one side and the constant is on the other side so that we have the standard form. Note that by convention the coefficient of x should be positive so:
y-x=-4 multiplying the entire equation by -1 we get:
x-y=4
