-3 to the 2nd power is -3 x -3 = +9 ( negative x negative = positive)

3 to the 2nd power means 3 x 3 3 x 3 = 9

The answer is 1. X=(3)^2 * (3)^-2 X=(3)^2 * 1/(3)^2 X=9 * 1/9 X=9/9 X=1

3 x 10 to the 5th power + 3 x 10 to the 4th power + 2 x 10 to the 2nd power

3 to the 2nd power times 3 to the 5th power = 3x3 x 3x3x3x3x3 = 2187

-12 x8 y8 / 3x4 y2 = -4 x4y6 First: divide -12 by 3 which equals -4 Second: divide x to the power of 8 by x to the power of 4 by subtracting the two powers ( 8-4 ) which will equal x to the power of 4 Third: divide y to the power of 8 by y to the power of 2 by subtracting the two powers ( 8-2 ) which will equal y to the power of 6

Yes. Since 'x' appears to the 2nd power, the equation is "second degree", or 'quadratic'.Also, since 'x' appears to the 2nd power, there are two solutions.x = +3 sqrt(3)x = -3 sqrt(3)
