simplify (4+2*(1+8x^9)-7+12)/4

simplify

\frac{4 + 2 \cdot ( 1 + 8 x ^{9} ) - 7 + 12}{4}

\frac{16 x ^{9} + 11}{4}

Solution steps

\frac{4 + 2 ( 1 + 8 x ^{9} ) - 7 + 12}{4}

Group like terms

= \frac{2 ( 1 + 8 x ^{9} ) + 4 - 7 + 12}{4}

Add the numbers:

4 - 7 + 12 = 9

= \frac{2 ( 1 + 8 x ^{9} ) + 9}{4}

Expand

2 (1 + 8 x^{9}) : 2 + 16 x^{9}

= \frac{2 + 16 x ^{9} + 9}{4}

= \frac{16 x ^{9} + 2 + 9}{4}

Add the numbers:

2 + 9 = 11

= \frac{16 x ^{9} + 11}{4}

\frac{( cos ^{2} ( t ) - 1 )}{2}

(x^{2} + 2 x y + y^{2}) - z^{2}

sec^{2} (x + y) + \frac{csc ^{2} ( 2 x + 2 y )}{3}

(6) x^{3} + y^{3} - 3 x y + 1

\frac{( c ) 1}{( 5 + 2 )}
