Question
I sure could use your help!!!!

Simplify:
49^-3/2

Thanks

Answer
The 3 means to cube it, and the 2 means to take the square root.
The negative sign then means to put it in a denominator.

Since it is known that 7*7 = 49, the square root of 49 is 7.

To cube 7, take 7*7^2 = 7*49 = 343 (that is, 280 + 63 = 343).

Putting that in the denominator gives 1/343.
