$z+(-0.72)=-2.5\\\\\text{Step 1}:\ x+(-0.72)+(-0.72)=-2.5+(-0.72)\qquad\text{ERROR}\\\\CORRECT\ IS:\ x+(-0.72)-(-0.72)=-2.5-(-0.72)\\\\\text{Step 2}:\ x=-2.5+0.72\\\\\text{Step 3}:\ x=-1.78$

Subtract, not add, -0.72 from both sides.

Express the prime number 31 in the form 2^p − 1 where p is a prime number and as a difference of two perfect squares using the i

stellarik [79]

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

32 = 2⁵

By subtracting 1 in bot sides

32-1 = 2⁵ -1

31 = 2⁵ -1

2⁵ -1 = 31

By comparing with

$2^p-1$

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)
