<h3>♁ Question :</h3>
- Find the distance between ( 5 , -6 ) and ( 3 ,4 ).
<h3>♁
Step by step explanation:</h3>
Let the points be A and B. Now,
- Let, A ( 5 , -6 ) ⇢ ( x₁ , y₁ )
- Let, B ( 3 , 4 ) ⇢ ( x₂ , y₂ )
Use the distance formula to determine the distance between A ( 5 , -6 ) and B ( 3 , 4 ).

Substitute the actual value of the points into the distance formula and then simplify.

Remember : The positive and negative integer are always subtracted but posses the sign of the bigger integer.

Remember : ( - ) × ( - ) = ( + )

Add the numbers : 4 and 6

Evaluate the power

Add the numbers : 4 and 100

units
Therefore , The distance between ( 5 , -6 ) and ( 3 , 4 ) is
units .
And we're done!
Hope I helped!
Have a wonderful time ! シ

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)
