-- 5 to the 6th power means (5 x 5 x 5 x 5 x 5 x 5) .To find the value of it, just do the multiplication.If you don't get 15,625 then you made a mistake.-- 4 to the 0 power is easy. Any number (except zero) to the zero power is ' 1 '.
2x2 - x - 15 = 0(2x + 5) (x - 3) = 0[2x + 5 = 0] and [x - 3 = 0]x = -5/2 and x = 3{-2.5, 3}
The domain is the real numbers except {0, 5}.
7^5 = 16,807 = (1 x 100000) + (6 x 10000) + (0 x 1000) + (8 x 100) + (0 x 10) + (7 x 1)
