3 - 5x - 2x = 3 - 7x
( 3 - 7x )2 = 9 - 42x + 49x2
2 to the second power, or (2^2), equals 4. Similarly, 1 to the second power, or (1^2), equals 1. Therefore, (2^2 = 4) and (1^2 = 1).
200
5 to the second power
It then equals 1/81
It equals 200 because 20x20 equals 200
2 to the second power, or (2^2), equals 4. Similarly, 1 to the second power, or (1^2), equals 1. Therefore, (2^2 = 4) and (1^2 = 1).

200
5 to the second power
It then equals 1/81
It equals 200 because 20x20 equals 200
The answer is 1, whatever the value of a.
Two to the fifth power multiplied by three to the second power equals 288.
