The answer is 1.
X=(3)^2 * (3)^-2
X=(3)^2 * 1/(3)^2
X=9 * 1/9
X=9/9
X=1
It is: 3-1*3-2 = 1/27
-3 to the 2nd power is -3 x -3 = +9 ( negative x negative = positive)

To calculate six times ten to the negative power, multiply 6 by the value of ten raised to the negative power. For example, if the power is -3, it would be 6 times 10 to the negative third power, which equals 0.006.
3 to the 2nd power times 3 to the 5th power = 3x3 x 3x3x3x3x3 = 2187
It is: 3-1*3-2 = 1/27
-3 to the 2nd power is -3 x -3 = +9 ( negative x negative = positive)
1 over 3 to the negative 2nd power is 9
3 times 10 to the 8th power divided by 7 times 10 to the negative 7th power equates to: 4.28571428571

a, a^3*a^-2 is a^3+-2 which equals just a
It is: 25
