Answer:
nice question...
so here we go
3^ -x = 1 / 3^x
so 1/ 3^x = 2 so 3^x = 1/2
we can write 3^2x as 3^x multiplied by 3^x right?..(law of exponents)
recall that 3^x =1/2
so now according to question we have to find the value of 3^2x = 1/2 * 1/2 = 1/4
Step-by-step explanation:
21 french fries/50 total = x french fries/350 total
Cross Multiply: (21 · 350) = (50 · x)
Divide both sides by 50: (21 · 7) = x
147 = x
