The equation is (7^x)^4 = (7^2 × 7^3)/ 7^3x
(7^x)^4 is equal to 7^(4x)
7^2 × 7^3 is equal to 7^(2+3) which gives 7^5
therefore;
7^5/7^3x is equal to 7^(5-3x)
Hence we get;
7^(4x)=7^(5-3x)
thus; 4x = 5-3x
7x = 5 (solving for x)
Therefore; x = 5/7
Answer:
r = 3
Step-by-step explanation:
34r + 3r =111
add;
34r + 3r = 37r
37r = 111
dividedboth sides by;

answer;
r = 3
The circumference of a circle can be found using the equation 2 π r
(2)(3.14)(4.5) = 28.26 (or 28 13/50 if you need it in fractions)
