Answer:

x = 19, y = -5

Step-by-step explanation:

x + y = 14 => x= 14-y

2x + 4y = 18 => 2(x+2y)=18 => x+2y=9

x+2y=9 => (14 - y) + 2y = 9

14 + y = 9 => y = -5

x + (-5) = 14 => x=19

Write the expression as a power

Natasha_Volkova [10]

The expression given in the question is expressed as a power is x^10

According to the law of indices, multiplication of powers becomes addition as shown:

$a^m \times a^n = a^{m+n}$

Given the following expressions;

$xx^4x^4x$

This can also be expressed as:

$= x \times x^4 \times x^4 \times x\\= x^{1+4+4+1}\\=x^{5+5}\\=x^{10$

This shows that the expression as power is x^10
