Find value of x:- 2²x 1=4²x-1?
Most Upvoted Answer
Find value of x:- 2²x 1=4²x-1?
Solution:
Given:
2²x+1 = 4²x-1
Method:
Using exponent laws, we can simplify the given equation.
2²x+1 = 4²x-1
2²x × 2¹ = 4²x ÷ 4¹
2²x+1 = 2²x
2²x × 2¹ = 2²x
2²x+1-2²x = 0
2²x (2¹ - 1) = 0
2²x = 0 or 2¹ - 1 = 1
Calculation:
2²x = 0 or 2¹ - 1 = 1
2²x = 0
2x = -2
x = -1
Answer:
x = -1

4 × 1 =. 16x - 1. ( as 2 square is 4 and 4 square is 16)
4+1 = 16x
5/16 = x
4 × 1 =. 16x - 1. ( as 2 square is 4 and 4 square is 16)
4+1 = 16x
5/16 = x
