Differentiate x^9(10.3)^x

[tmatthes]

Hi, I need help figuring out how to perform this on my calculator. I have a Texas Instruments TI 89. The answer they are looking for "Differentiate x^9(10.3)^x" is below:

g'(x)=x^9 * ln10.3 * (10.3)^x+9x^8(10.3)^x

Use \(\displaystyle (10.3)^x = exp(x \ ln(10.3) )\).
