10.) Which of the following is the value of 3 √ 0.000064?
0.000064 is rewritten as 3 √ 64 X 10 ^ -6 (this I understand)
√ 4 x 10 ^ -2 (this is where I am lost, I understand square root of four because 4x4x4 = 64, but where is the 10 to the negative second power coming from?)
√4 x √ 10 ^ -2
2 x 10 ^ -1 (also here, why does 10 to the negative second power become 10 to the negative one power?)
= 0.2
