1/32^(1/5)
^1/5 means 5√32 = 2
so the answer is 1/2 or 0.5
For the first one at the top it’s 300 and 575 then going down it’s 17.21, 63.33, and then 184.68
Answer:
Step-by-step explanation:
<u>Let the cost of a sheet be s and cost of a blanket be b</u>
<u>From the first equation we get:</u>
<u>Substitute in the second equation</u>
- s + 4*(41 - 2s) = 80
- s + 164 - 8s = 80
- 7s = 84
- s = 12
<u>Then</u>
