-23
The value of a2+b2 = 0.05
The value of a3+b3 = 41.73
Concept: (a+b)2 = a2+b2+2ab
(a-b)2 = a2+b2-2ab
(a+b)3 = a3+b3+3a2b+3ab2
(a-b)3 = a3-b3-3a2b+3ab2
(I) a²+b²=(1/7-4✓3)²+(1/7+4✓3)²
⇒ ( 1/49 - 48) +(1/49 + 48)=(1-2352/49) + (1+2353/49)
⇒ -47.97 +48.02= 0.05
(ii) a³+b³=(1/7-4✓3)³+(1/7+4✓3)³
⇒(-6.78)³ +(7.07)³
⇒-311.66 +353.39= 41.73

Holigina, this is the solution:
Let's recall that √x = x ^(1/2)
Therefore,
√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)
The correct answer is C. 1
52. (x - 2) cause the graph to shift to the right 2 units
So key points from y = -3x - 1 will have 2 added to the x-coordinate
(0, -1) will turn into (2, -1) and (1, -4) will turn into (3, -4)
The correct answer is J.
You could also substitute (x - 2) into the equation y =-3(x - 2) -1 and simplify
y = -3x + 6 - 1
y = -3x + 5
plot that b (5) on the y-axis and drop down 3, move right 1 and plot another point
