9-9.

Solve each equation for $n$. Give both exact and approximate answers. Write your approximate answers accurate to two decimal places.

1. $n^{3} = 49$

$\sqrt[3]{49} \approx 3.66$

1. $3^{n} = 49$

Take the log of both sides to bring down the exponent.

1. $3^{n+1}=49$

Use the same method from part (b).
