Raj is simplifying (5 Superscript 4 Baseline) cubed using these steps: (5 Superscript 4 Baseline) cubed = 5 Superscript 4 Baseline times 5 Superscript 4 Baseline times 5 Superscript 4 Baseline = 5 Superscript 4 + 4 + 4 Although Raj is correct so far, which step could he have used instead to simplify the expression (5 Superscript 4 Baseline) cubed? 5 Superscript 4 times 3 Baseline = 5 Superscript 12 5 Superscript 4 + 3 Baseline = 5 Superscript 7 4 Superscript 5 times 3 Baseline = 4 Superscript 15 4 Superscript 5 + 3 Baseline = 4 Superscript 8

A

Step-by-step explanation:

Because you need to multiply them to get your solution of 5 to the power of 4 times 3 to get 5 to the power of 12

A (3 t) Superscript 4 = 3 t Superscript 4

Step-by-step explanation:

The answers are the following:
1. y − 4 = −one half(x + 6)
Solution:
the point is 4
y=4
y-4=0
the slope is,
y2-y1 / x2-x1
0-4/ 2-(-6)
-4/8 or -1/2

2. The answer is y = one half x + 6
 y − 3 = one half(x + 6)
y-3= one halfx+3
y=one halfx+3 +3
y = one half x + 6

3. The solution for y − 4 = three fourths(x + 8) is,
y-4 = 3/4x + 3/4(8)
y-4 = 3/4x +6
y-4-6=3/4x
y-10=3/4x
-3/4+ y =10
further solution for its standard form is 
(4)y-3/4x =10(4)
y-3x=40
y-3x-40 = 0
but from the choices, the answer is
−three fourthsx + y = 10
