Question 1043990
<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 7^{-x}\ =\ \frac{1}{7^x}]


so


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 7^{x}\ =\ 4]


Then


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 49^x\ = \left(7^x\right)^2]


Substitute *[tex \Large 4] for *[tex \Large 7^x] and do the arithmetic.
