    TI-Nspire CX CAS

    Hi,

    I have an equation I was wondering if the TI-Nspire can do for me. It is

    100^a=10^b
    what is a/b?

    If anyone knows how to do that on the Nspire, please let me know. Thank you!

    much easier without a calculator ...

    $100^a = (10^2)^a = 10^{2a} = 10^b \implies 2a = b \implies \dfrac{a}{b} = \dfrac{1}{2}$
