Question

prove that 4 + 4 = 7​

Answer 1

Step-by-step explanation:

Simply continue this process until the number can no longer be reduced: we see, then, that 7 (seven) has five letters, so 7 equals 5

Answer 2

Answer:

4=5 is not possible.

However, consider the below mentioned:

-20 = -20

25–45 = 16–36

(5)^2 - 2*5*9/2 + (9/2)^2 = (4)^2 - 2*4*9/2 + (9/2)^2

(5–9/2)^2 = (4–9/2)^2

taking square roots both sides,

5–9/2 = 4–9/2

cancelling 9/2 both sides,

5 = 4 This proves that 4=5 but logically and mathematically , it is not right.

When we take square roots either ways, the value should be equal to + or - value .

Like here,

either (5–9/2) = (4–9/2) or (5–9/2) = -(4–9/2)

If (5–9/2) = (4–9/2) would give you 5=4 which is not true.

If (5–9/2) = -(4–9/2) => 5–9/2 = -4+9/2 =. 9=9( This is True)
