1 = x^2
+/- sqrt(1) = sqrt(x^2)
{sqrt(1) = 1} {sqrt(x^2) = x}
+/- 1 = x
Final answer: x= 1 or -1
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).
If T2 = 78, then T = 78(1/2) or the square root of 78, or about 8.83.
It then equals 1/81
8 1/3 = ab^-1, 1.8 =ab^2
1 over 5^2. which is 1/25

The answer is 1, whatever the value of a.

1 watt is equal to 1 joule per second. This means that 1 watt of power equals 1 joule of energy expended over a period of 1 second.

What equals 1 second
One third to the second power is calculated by squaring one third. This is expressed mathematically as (1/3)², which equals 1/9. Therefore, one third to the second power is 1/9.
2sinx+1 equals 0
It could be either, depending on what x equals. If x = 9, 8 will solve the first one. If x = 1, 8 will solve the second one.
