Find x: (2/7)-8 (7/2)-2CORRECT ANSWER: (2/7)2x

Answer»

-step explanation:GIVEN: equation(2/7)^-8 x (7/2)^-2 = (2/7)^2xAs per the law of exponent (a)^-b = (1/a)^BSO, LHS = (2/7)^-8 x (2/7)^2 ( MAKING the base same = the base of RHS)=(2/7)^-6 …………..LHS ( by ADDING the exponent in multiplcation , with the same base)&(2/7)^2x ……………RHSSo equation becomes(2/7)^-6 = (2/7)^2x
