Started online calculus. Tough learning alone.
Anyone know how to solve x^-2.2=4127
also 4e^(x-2)=1325
1.) I would rewrite the equation as:
$\displaystyle x^{-\frac{11}{5}}=4127$
Raise both sides to a power of $\displaystyle -\frac{5}{11}$. What do you find?
2.) Divide through by 4 to get:
$\displaystyle e^{x-2}=\frac{1325}{4}$
Convert from exponential to logarithmic form. What do you find?
