<span>√63 = 3√7 is your answer</span>
1500 is the answer I did this a while ago I think not sure
You might have made an error the first time you solved for x. I got x = -0.5.
When you have your log base 4, the way you cancel that out is by making 4 the base on both sides, so you get 4^(log4) to reduce to 1, and you're left with:
2x + 3 = 4^(1/2) ... Simplify
2x + 3 = 2
2x = -1
x = -1/2
If you plug that back in, everything checks out. Maybe double check your use of logarithm/exponent properties?
As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
