#dy/dx=(10ln(x)+10)x^(10x)#

Explanation:

#y=x^(10x)#

Take the logarithm of both sides then use implicit differentiation:

#lny=ln(x^(10x))#

#->lny=10xln(x)# (Using the laws of logs)

Now implicitly differentiate via the product rule:

#1/ydy/dx=10ln(x)+10x*1/x=10ln(x)+10#

Multiply by #y#:

#dy/dx=(10ln(x)+10)y#

Substitute #y# back in:

#dy/dx=(10ln(x)+10)x^(10x)#
