solvefor x,4-3^x=0

Solution

solve for

x, 4 - 3^{x} = 0

Solution

x = \frac{2 ln ( 2 )}{ln ( 3 )}

+1

Decimal Notation

x = 1.26185 \dots

Solution steps

4 - 3^{x} = 0

Add

3^{x}

to both sides

4 - 3^{x} + 3^{x} = 0 + 3^{x}

Simplify

4 = 3^{x}

Apply exponent rules

ln (4) = x ln (3)

Solve

ln (4) = x ln (3) : x = \frac{2 ln ( 2 )}{ln ( 3 )}

x = \frac{2 ln ( 2 )}{ln ( 3 )}

Popular Examples

128 = 2^{n}

((8^x)^x)/(32^x)=4

\frac{( 8 ^{x} ) ^{x}}{3 2 ^{x}} = 4

28 \cdot 3^{5 x} = 252

5*6^{x+7}=8*9^{x-10}

5 \cdot 6^{x + 7} = 8 \cdot 9^{x - 10}

solvefor x,e^{3x}=5 solve for

x, e^{3 x} = 5
