How do you solve 2x+1=642^{x+1}=642x+1=64 without using logarithms?
A
- Rewrite 64 as 262^626
- Equate indices: x+1=6x+1=6x+1=6
- x=7x=7x=7
B
- Rewrite 64 as 262^626
- Equate indices: x+1=6x+1=6x+1=6
- x=5x=5x=5
C
- Rewrite 64 as 252^525
- Equate indices: x+1=5x+1=5x+1=5
- x=4x=4x=4
D
- Rewrite 64 as 262^626
- Equate indices: x=6</li><li>x=6\text{}</li><li>x=6</li><li>x=6$
