Evaluate π equals nine multiplied by π to the power of ln seven.
So if we take a look at what weβve got, weβve got π equals nine multiplied by π to the power of ln seven. Well, to solve this, we can use an identity we know. And our identity is that π to the power of ln π₯ is equal to π₯. So therefore, we can say that π raised to the natural logarithm of π₯ will just give us the result of π₯. And if we apply this to ours, what weβre gonna have is nine multiplied by seven. And thatβs because seven was our π₯ because it was ln seven or the natural algorithm of seven.
So therefore, we can say that π is equal to 63.
