Hello from MrBillDoesMath!
Answer:
1/64
Discussion:
(2^3) ^ (-2) => 2^3 = 2 * 2 *2 = 8
= 8^(-2) => negative exp gives reciprocal of time to same
power
= ( /8)^2 => 8*8 = 64
= 1/64
NOTE; the answer shown selected in the diagram is incorrect as the correct result is a positive, NOT negative, number. The second choice is the correct one.
Thank you,
MrB

Step-by-step explanation:
the following things are clear : opposite sides are of equal length, the sum of all angles in a square, rectangle or general parallelogram is 360 degrees, and opposite angles are equal.
so,
y² + 7 = 32
y² = 25
y = 5
2y² = k
2×5² = k
50 = k
the opposite angle of 150 is also 150 degrees.
the opposite angle of x is also x.
so, we have as sum of angles
360 = 150 + 150 + x + x = 300 + 2x
60 = 2x
x = 30 degrees
