simplify 2^x+2^x+3

Solution

simplify

2^{x} + 2^{x} + 3

2^{1 + x} + 3

Solution steps

2^{x} + 2^{x} + 3

Add similar elements:

2^{x} + 2^{x} = 2 \cdot 2^{x}

= 2 \cdot 2^{x} + 3

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

2 \cdot 2^{x} = 2^{1 + x}

= 2^{1 + x} + 3

\frac{( \frac{1}{9} x ) ^{2} - 2}{3 x - 1}

\frac{( 36 x ^{4} + 30 x ^{3} + 36 x ^{2} )}{( 6 x ^{3} )}

t^{2} - e^{- 2} t + cosh^{2} (t)

2 m \cdot (- m^{2} - m + 5)

(1 - 3 i)^{3} + a (1 - 3 i)^{2} - b (1 - 3 i) - 20
