expand 4(a(2+2^t+3^t))

expand

4 \cdot (a \cdot (2 + 2^{t} + 3^{t}))

8 a + 2^{2 + t} a + 4 \cdot 3^{t} a

Solution steps

4 (a (2 + 2^{t} + 3^{t}))

Remove parentheses:

(a) = a

= 4 a (2 + 2^{t} + 3^{t})

Distribute parentheses

= 4 a \cdot 2 + 4 a \cdot 2^{t} + 4 a \cdot 3^{t}

= 4 \cdot 2 a + 4 \cdot 2^{t} a + 4 \cdot 3^{t} a

Simplify

4 \cdot 2 a + 4 \cdot 2^{t} a + 4 \cdot 3^{t} a : 8 a + 2^{2 + t} a + 4 \cdot 3^{t} a

= 8 a + 2^{2 + t} a + 4 \cdot 3^{t} a

(1 + 3 j) (1 - 3 j)

\frac{( x - 1 ) ( x - 2.5 )}{( x - 3 )} - 1

(ni + 2)^{2}

\frac{2 ( x - 3 ) \cdot e ^{8 x}}{( x + 5 ) ^{7}}

(\frac{1}{x} + 3 x^{2})^{5}
