Answer:
31 = 2⁵ -1
31 = 16²- 15²
Step-by-step explanation:
As we know that
2¹=2
2²= 4
2³= 8
2⁴= 16
2⁵=32
So
32 = 2⁵
By subtracting 1 in bot sides
32-1 = 2⁵ -1
31 = 2⁵ -1
So
2⁵ -1 = 31
By comparing with
p= 5
As we know that
15²= 225
16² = 256
16²- 15² = 256-225 = 31
16²- 15² = (16+15)(16-15)
31 = (16+15)(16-15)
If you want to find out ..for example.. cube root of 8..just put it in the calculator!
Or you could power it by 1/3 ...which is the same thing as cube rooting it.
(Even though I need the calculator in both the cases..)
Hope this helps though :)

Answer:
5/7 gallons of water for each rose bush
Step-by-step explanation:
we know that
To find out the amount of water that Elena give to each rose bush, divide the total gallons of water by the number of rose bushes
so
therefore
5/7 gallons of water for each rose bush
951 1404 393
Answer:
61.03 N at 35° above the horizontal
Step-by-step explanation:
The forces operate at right angles, so the Pythagorean theorem can be used to find the magnitude of the resultant:
||F1 +F2|| = √(50² +35²) = √3725 ≈ 61.03 . . . . newtons
The angle (α) relative to F2 can be found using the tangent relation.
tan(α) = 50/35
α = arctan(50/35) ≈ 55.008°
Then the angle relative to the horizontal reference line is ...
55.0° -20° = 35.0°
The resultant is about 61.03 N at an angle of 35° above the horizontal.
