Hi, 1. 2^(5/2) - 2^(3/2) = √(2^5) - √(2^3) = √{(2^4)•2} - √{(2^2)•2} = 2²•√2 - 2•√2 = 4•√2 - 2•√2 = 2•√2 2.(1/x) = (1/a) = (1/b), where a â‰* b x = a = b, where a â‰* b so x = { } or NULL 3. 3•x² - 2•x + 7 = 0 ... divided by 3 .... x² -...

Hi, 1.) Use Physic Formula : Work = Force • distance distance = Work / Force distance = 8.8 • 10^-4 J / 3.4 • 10^-4 N distance = 2.59 meter so far = 2.59 meter 2.) high = Work / Force high = 6222 J / 2595 N high = 2.39 meter so high = 2.39 meter Hope this...
