The value of x is 3

Step-by-step explanation:

Given:

x^3 = 27

To Find:

x = ?

Solution:

We Know that

$a = (a^3)^\frac{1}{3}$

$a = (a)^\frac{3}{3}$

We can write 27 as $3 \times 3 \times 3$ = 3^3

Taking cube root on both sides

$(x^3)^{\frac{1}{3} }= (3^3)^{\frac{1}{3}}$

$x^{\frac{3}{3}} = 3^{\frac{3}{3}}$

x^1 = 3^1

x = 3

$162.50 per month for the next 4 years

Step-by-step explanation:

Here are the options to this question :

Save $270.83 per month for the next 4 years

Save $162.50 per month for the next 4 years

Save $650.00 per month for the next 4 years

Save $108.33 per month for the next 4 years

If Devon's parents would give him $5,200 for his first year of tuition, Devon needs to save a minimum of :

$13,000 - $5,200 = $7,800

If he saves per month for the next four months, he would save 48 times ( 12 months in a year multiplied by 4 years)

The minimum he should save per month = $7800 / 48 = $162.50
