• This Question is Open
1. myininaya

$x^{7 \cdot ? }=4000^?$ We need to figure out how we can get just x on that one side recall x=x^1 so what can we multiply by 7 to get 1?

2. ngawang

can u try to do it

3. myininaya

Can you tell me what we can multiply to 7 so we get 1?

4. ngawang

1/7

5. myininaya

so you would have $(x^7)^\frac{1}{7}=4000^\frac{1}{7}$
