Find the derivative on the value of x=-4 y=(6x-5)√(8x-3)

Question

Find the derivative on the value of x=-4

`y=(6x-5)√(8x-3)`

Answer 1

`\\ \sf\longmapsto y=(6x-5)√(8x-3)`

`\\ \sf\longmapsto y=6(-4)-5√(8(-4)-3)`

`\\ \sf\longmapsto y=-24-5√(-32-3)`

`\\ \sf\longmapsto y=-29√(-35)`

`\\ \sf\longmapsto y=-29* 35i`

`\\ \sf\longmapsto y=-1015i`
