Question

y=(5+7x)⁶find dy/dx​

Answer 1

Answer:

dy/dx=42(5+7x)^5

Step-by-step explanation:

y=(5+7x)^6

dy/dx=6(5+7x)^5 d/dx(5+7x)

        =6(5+7x)^5   x 7

        = 42(5+7x)^5

MARK ME BRAINLIST!!!

Answer 2

Answer:

• y=(5+7x)⁶

suppose,

• 5+7x=t so, y=t⁶
• Dt/Dx=7 Dy/Dt=6t⁵
• therefore,
• Dy/Dx=Dt/Dx*Dy/Dt
• =7*6t⁵
• =42t⁵
• =42(5+7x)⁵ [put,t's value]✓
