Paul earns $7 per hour at the bagel shop and $12 per hour mowing lawns. he needs to earn at least $120 per week, but he must work less than 30 hours per week. write and graph the system of linear inequalities that describes this situation.

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
