9-9.

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

$n^{3} = 49$
Answer (a):
$\sqrt[3]{49} \approx 3.66$

$3^{n} = 49$
Hint (b):
Take the log of both sides to bring down the exponent.

$3^{n+1}=49$
Hint (c):
Use the same method from part (b).
