Solution

I think your question has a problem ,if you want correct better upload image of problem
If your question is exactly as follows ,solution is given below
if a =-2,b=-3 ,c=4 find 5 a^2b^3c+3a^3b^2c^2-(-2)^2(-3)^244
a =-2,b=-3 ,c=4
5a^2b^3c=5-2^-6^12=(-10)^612=(-10)^72
3a^3b^2c^2=-6^-6^8^2=(-6)^-682=(-6)^-96
(-2)^2=4
(-3)^244=(-3)^32
(-2)^2(-3)^244=4(-3)^32
Therefore 5 a^2b^3c+3a^3b^2c^2-(-2)^2(-3)^24*4=(-10)^72+(-6)^-96-4(-3)^32
=10^72+5.0410^74+7.4110^15
=5.04110^75
