# Algebra Sq Rt

I have a sq rt sign with a 3 on the left side. That means I'm looking for the cube of the number inside the square root? That number is 189xto the 8th power. So I multiply 189x 8 times before I find the cube or do I find the cube of 189?

1. The cube root of 189^8 can be calculated either by taking the cube root of 189*189*189*189*189*189*189*189, or by multiplying the cube root of 189 together 8 times.
Either way, you should get about 1,176,427. It is an irrational number with no end to the decimals.
If you don't like cube root radical signs, which are hard to type, it could also be written
189^(8/3)
