Answer:

Step-by-step explanation:

$\frac{1}{4}x^{2}= \frac{1}{2}x +2\\\frac{1}{4}x^{2}- \frac{1}{2}x -2=0\\\frac{x^{2}-2x-8 }{4}=0\\\\x^{2}-2x-8=0\\ x^{2}-4x+2x-8=0\\x(x-4)+2(x-4) = 0\\(x-4) (x+2) = 0\\SO, \\x= 4 or x= -2$

what is a power rule for exponents ?

$(a^m)^n=a^{mn}$ is known as the power rule for exponents. Exponent times power is how you raise a number with an exponent to a power.

A number's exponent demonstrates how many times we are multiplying a given number by itself. 3^4, for instance, indicates that we are multiplying 3 by four. 3*3*3*3 is its expanded form. The power of a number is another name for an exponent. It could be an integer, a fraction, a negative integer, or a decimal.

$(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7$

Here, we have used the rule $(a^m)^n=a^{mn}$
