\[(8x)^0(7^7)(7^x)=7^6\] \[1(7^{7+x})=7^6\] \[7+x=6\] \[x=-1\]

Thanks , what about 2 ?

OpenStudy (mertsj):

Did you try it yet?

OpenStudy (mertsj):

Remember y^5 divided by y^5 = 1

OpenStudy (anonymous):

No its confusing idk how :{

OpenStudy (anonymous):

6^(-x)y^5 / y^5 = 6^8 = 6^-x * y^5 / y^5 = 6^8 y^5 / y^5 = 1 it leaves you with 6^-x = 6^8

OpenStudy (mertsj):

\[\frac{6^{-x}y^5}{y^5}=6^8\] \[6^{-x}=6^8\] \[-x=8\] \[x=-8\]

OpenStudy (mertsj):

\[\frac{8^5}{8^x}=8^7\] \[8^{5-x}=8^7\] \[5-x=7\] \[x=-2\]
