# Can u solve these problems ??1.If x to the power 4 +  y to the power of 4 = 47x square y square . show that log ( x square + y square / 7 ) = logx + log y2. If x square + y square = 27xy , show that log ( x-y/5) = 1/2 ( log x + log y )3. If x square + y square = z square , show that log of  z - y to the base x + log of z+y to the base x = 24. If a to the power of x = b to the power of y = c to the power of c and y square = xz , prove that log of a to the base b= log of b to the base c 5. Prove that 1/ log of xy to the base x + 1/ log of xy to the base y = 16. If a cube + b cube = c cube , show that log of c-b to the base a + log c square + cb + b square to the base a = 3 7. If a to the power of 4 + b to the power of 4 = c to the power of 4 , prove that log of c-b to the base a + log of c+b to the base a + log of c square + b square  to the base a = 4 8. If log x-y = log x - log y , show that x= y square / y-19. If log x square + y square = log 2 + log x + log y , show that x = y
