You give 1/2 up a $46,000 salary to go back to school for 5 years. The total cost for going to school is $22,000. How much money
Ket [755]

The individual needs to earn $74,750 salary per year in order to recover the investment in 4 years.

What salary amount makes the individual as they were without a salary cut?

By the time the individual resumes back for work after 5 years, they need to earn their previous salary of $46,000 and recover the lost salaries, which is half of $46,000 lost in the last 5 years.

Total salaries lost=1/2*$46,000*5years

Total salaries lost=$115,000

Because the salaries lost needs to be recovered over 4 years, the extra earnings over and above the $46,000 in 4 years is the total salaries lost divided by 4 years

extra salary per year=$115,000/4

extra salary per year=$28,750

Total salary now=prior salary+ extra salary per year

Total salary now=$46,000+$28,750

Total salary now=$74,750

When I write my expression in rational exponent form, what is the fraction that goes with the base of 10?
blsea [12.9K]

Answer: Choice A

\sqrt[4]{3^3}

The fourth root of 3^3

=============================================

Explanation:

The exponent of 1/4 means "fourth root", so,

3^{1/4} = \sqrt[4]{3}

The outer exponent 3 can be moved inward like this

\left(3^{1/4}\right)^3 = 3^{1/4*3} = 3^{3/4}

Then we can use the rule

x^{m/n} = \sqrt[n]{x^m}

This means

3^{3/4} = \sqrt[4]{3^3}
