FIND THE VALUE OF X ?
(2/7)^-8*(7/2)^-2=(2/7)^X
Read Solution (Total 6)
-
- (2/7)^-8*(7/2)^-2=(2/7)^x
Now, (7/2)^8*(2/7)^2=(2/7)^x
on solving,
(7/2)^6=(2/7)^x
(2/7)^-6=(2/7)^x
Thus, x=-6. - 10 years agoHelpfull: Yes(16) No(0)
- (2/7)^-8*(7/2)^-2=(2/7)^x
(2/7)^-8*(2/7)^2=(2/7)^x
Now as the bases are same we can solve the powers
-8+2=x
-6=x or x=-6. - 10 years agoHelpfull: Yes(7) No(0)
- x=-6
bases are equal so powers are add - 10 years agoHelpfull: Yes(5) No(1)
- (2/7)^-8*1/(7/2)^2=(2/7)^x
(2/7)^-8*(2/7)^2=(2/7)^x
==>x=-6 - 10 years agoHelpfull: Yes(3) No(0)
- x=-6
when bases are equal and multiply thm then their powers are add - 10 years agoHelpfull: Yes(2) No(0)
- bases are equal so ....
-8+(-2)=x
-10=x
x=-10 - 10 years agoHelpfull: Yes(1) No(7)
