simplify 3(3e^{3x}cos(2x))

Solution

simplify

3 (3 e^{3 x} cos (2 x))

Solution

9 e^{3 x} cos (2 x)

Solution steps

3 (3 e^{3 x} cos (2 x))

Apply exponent rule:

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

3 \cdot 3 = 3^{1 + 1}

= 3^{1 + 1} e^{3 x} cos (2 x)

Add the numbers:

1 + 1 = 2

= 3^{2} e^{3 x} cos (2 x)

3^{2} = 9

= 9 e^{3 x} cos (2 x)
