How do I simplify (2x1/4) -4th power?
alina1380 [7]
Since the 2 and x^1/4 are multiplying we can do the math separately and then just multiply them afterwards

2^-4 is the same as 1/(2^4) which is 1/16

(x^1/4)^-4    (POWER RULES REVIEW)
                          2 exponents of same base you just add (basically multiply                                                                                                              the two)
so x^(1/4x-4)  = x^(-1)

which is just 1/x

so the answer is 1/16x

ra1l [238]

Answer:

482.70

Step-by-step explanation:

First, find out how much he earned per hour last week. 576.56 divided by 43 is 13.41.

Second, multiply his hourly earnings by 1.2, 1.2*13.41=16.09 So he earns 16.09 per hour

Lastly, multiply 16.09 by 30, 16.09*30=482.7 So he earns about $482.70 each week.
