simplify x^3+(2y)^2

Solution

simplify

x^{3} + (2 y)^{2}

x^{3} + 4 y^{2}

Solution steps

x^{3} + (2 y)^{2}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

(2 y)^{2} = 2^{2} y^{2}

= x^{3} + 2^{2} y^{2}

2^{2} = 4

= x^{3} + 4 y^{2}

49 \cdot (2 x + 3 y)^{2} - 70 (4 x^{2} - 9 y^{2}) + 25 \cdot (2 x - 3 y)^{2}

(x - 1) (x + 3) - (\frac{( 2 x - 2 )}{( x + 2 )})

\frac{( a ^{3} )}{( ( a - b ) ( a - c ) )} + \frac{( b ^{3} )}{( ( b - a ) ( b - c ) )} + \frac{( c ^{3} )}{( ( c - a ) ( c - b ) )}

x^{6} - 15625

(b^{x + 1} - 3) (b^{x + 1} - 1)
