Answer:
Step-by-step explanation:
x = 2 and y = 5
[tex]3) -4x^{-2}* 3y^{0} = -4*\dfrac{1}{x^{2}}*3*1[/tex] [tex][ y^{0} = 1][/tex]
Now plug in x = 2
[tex]= -4 * \dfrac{1}{2^{2}}= -4 * \dfrac{1}{4}[/tex]
= - 1
[tex]4) 2x^{0}*y^{-2} = 2*1 * \dfrac{1}{y^{2}}= 2*\dfrac{1}{y^{2}}[/tex]
Now, plugin y= 5
[tex]= 2 * \dfrac{1}{5^{2}}=\dfrac{2}{25}[/tex]
