Choose the correct simplification.

x^3y^6z^3 is correct

Step-by-step explanation:

Taking an exponent to the power of an exponent means multiplying the exponents together.

So y^2^3 is the same as y^(2*3) or y^6

Hope that made sense!

The number of the increase is  (216 - 75) = 141

As a fraction of the original number, that's    141/75 = 1.88

To change any number to a percent
move the decimal point two places that way ==> .

               1.88  =  188% .

The increase from 75 jobs to 216 jobs, is an increase of 141 jobs.

141 is 1.88 times as much as 75 ... an increase of 188% .
