Question

If 4^2-x=3, then 4^2x-1=? Step by step solutions pls

Answer 1

4^2-x=3
16-x=3
x=13

4^2 (13)-1=x
208-1=x
x=207

Answer 2

\[4^{2}-x = 3\]\[16-x = 3\]\[-x = -13\]\[x=13\]Then just plug in x into the 2nd equation and solve:\[4^{2 \times 13} - 1 = y\]\[4503599627370495 = \]

Answer 3

y

Answer 4

oh sorry i misread the question

Answer 5

Your answer seems a lot less "out there." I solved the question that was posted, but the question was probably formatted incorrectly, so you're probably right.

Answer 6

is it 4^(2-x) or (4^2)-x

Answer 7

uh huh thankx

Answer 8

then alex is right

Answer 9

if the equation was 4^(2-x)=3 then :
(4^(2-x))^2=3^2
4^(4-2x)=9
4^4=9*4^2x
4^3=9*4^(2x-1)
4^(2x-1)=64/9

Answer 10

why did you square the 4^(2-x) and the 3? but you got the right answer.

Answer 11

If 4^2-x=3, then 4^2x-1=? Step by step solutions pls
\[4^2-x=3\]
\[16-x=3\]
\[-x=3-16\]
\[-x=-13\]
\[x=13\]\[4^2x-1=16(13)-1=207\]
