Take the natural logarithm of both sides of the equation to remove the variable from the exponent. ln(ey) = ln(x) ln ( e y) = ln ( x) Expand the left side. Tap for more steps...Now it only remains to nd E [X 2 j Y = 2] and E [X j Y = 2] . Applying integration by parts twice we have E [X 2 j Y = 2] = 1 2 x 2 6 e 2 x 6 dx = x 2 e 2 x 6 1 2 12 xe 2 x 6 1 2 12 6 e 2 x 6 1 2 = 4+24+72 = 100 : On the other hand, again applying integration by parts we get E [X j Y = 2] = 1 2 x 6 e 2 x 6 dx = xe x 2 6 1 2 6e x 2 6 1 2 = 2+6 = 8 :.
