Rewrite 80 as its prime factor
Square root (2x2)x(2x2)x5

Group the same prime factors into pairs.
(2x2)x(2x2)x5

Rewrite each pair in exponent form.
2(2) x 2(2) x 5

Use this rule: square root of x(2) = x.

(2x2) square 5

Simplify 4 square 5

Decimal form: 8.944272

F(x)=x+3 , G(x)=x^2-2<br> (F/G)(-1)-G(3)

trapecia [35]

$f(x)=x+3;\ g(x)=x^2-2\\\\\left(\dfrac{f}{g}\right)(-1)-g(3)=?\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\g(3)=3^2-2=9-2=7\\\\f(-1)=-1+3=2\\\\g(-1)=(-1)^2-2=1-2=-1\\\\\left(\dfrac{f}{g}\right)(-1)-g(3)=\dfrac{2}{-1}-7=-2-7=-9$
