Need Exponent Help

OpenStudy (eyust707):

throw it my way

OpenStudy (anonymous):

\[2^{2x} \times 2^{3} = 2 \] what is the value of x

OpenStudy (eyust707):

we can use this property

OpenStudy (eyust707):

since \[2 = 2^1\] \[2^{2x} * 2^3 = 2^1\]

OpenStudy (anonymous):

yes, but then what would be the value of x

OpenStudy (mathmagician):

2^(2x+3)=2^1 2x+3=1 x=-1

OpenStudy (eyust707):

therefore 2x + 3 = 1

OpenStudy (eyust707):

then solve for x

OpenStudy (eyust707):

2x = -2

OpenStudy (eyust707):

x = -1

OpenStudy (eyust707):

manyo do you understand that?

OpenStudy (anonymous):

yes, but so we would have two exponets. 2 and -1

OpenStudy (anonymous):

and the two exponents would be multiplied.

OpenStudy (eyust707):

\[2^{2x} * 2^3 = 2^1\]

OpenStudy (eyust707):

if we replace the x with a -1 we get \[2^{-2} * 2^3 = 2^1\]

OpenStudy (eyust707):

and we can check our answer this way since -2 + 3 = 1

OpenStudy (eyust707):

which satisfies this property
