Question

(0,49)^x+2 = 1 3/7 help

Answer 1

$0,49^{x+2} =1 \frac{3}{7}$
$0.49^{x+2} = \frac{10}{7}$
$(\frac{7}{10}) ^{2x+4} =( \frac{7}{10} ^{-1} )$
2x+4= - 1
2x= - 5
x= - 2.5

Answer 2

To solve the equation (0,49)^x+2 = 1 3/7, we need to follow these steps:

Step 1: Rewrite 1 3/7 as an improper fraction. 1 3/7 = (7 * 1 + 3) / 7 = 10/7

Step 2: Subtract 10/7 from both sides of the equation. (0.49)^(x + 2) - 10/7 = 0

Step 3: Convert 0.49 to a fraction. 0.49 = 49/100

Step 4: Raise both sides of the equation to the reciprocal of (x + 2). [(49/100)^(x + 2)]^(1/(x + 2)) = 0^(1/(x + 2))

Simplifying the left side: 49/100 = 0

Step 5: Solve for x. Since 49/100 = 0 is not possible, there is no real solution for x in this equation.

Therefore, the equation (0,49)^x+2 = 1 3/7 has no real solutions.
