What to the tenth power can get you 300

OLEGan [10]

Answer:

1.7689 (rounded to 4 decimal places)

Step-by-step explanation:

Let the number we are seeking be "x", thus we can write the equation as:

$x^{10}=300$

Since we have raised "x" to the "10th power", to get "x" back again, we need to take 10th root. Same goes for right side, we take 10th root of 300. We will get our answer. The process shown below:

$x^{10}=300\\\sqrt[10]{x^{10}} =\sqrt[10]{300} \\x=\sqrt[10]{300} \\x=1.7689$

hence, 1.7689 raised to 10th power will give us 300

Two kilos of taronges and three kilos of mandarins cost 11.50 euros. Three kilos of taronges and two of mandarins cost 11 euros.

Illusion [34]

Answer:

Hence the pricing for each product will be taronges with 2 euros and mandarins with 2.5 euros.

Step-by-step explanation:

Given:

2 kg of taronges and 3 kg mandarins cost 11.5 euros

3kg taronges and 2 kg mandarins cost 11 euros

To Find:

Price for each product

Solution:

Consider 

Taronges =x euros

Mandarins=y euros

So by given condition,

$2x+3y=11.5$ ....................equation(1)

and $3x+2y=11 ...$ ...........equation (2)

So , using substitution method,

$3x=11-2y$

$x=11-2y/3$ .......equation (3)

Using above value in equation(1) we get ,

$2(11-2y)/3+3y=11.5$

$y=(11.5*3-22)/5$ )

y=2.5 euros

Using above value in equation(3) we get ,

$x=(11-2y)/3$

$x=(11-2*2.5)/3$

$x=(11-5)/3$

x=2 euros
