simplify (x+2/3)^2

Solution

simplify

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

\frac{( 3 x + 2 ) ^{2}}{9}

Solution steps

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

Simplify

x + \frac{2}{3} : \frac{3 x + 2}{3}

= (\frac{3 x + 2}{3})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{( 3 x + 2 ) ^{2}}{3 ^{2}}

3^{2} = 9

= \frac{( 3 x + 2 ) ^{2}}{9}

x^{9} + x^{6} + x^{3}

(2 cos (2 t))^{2}

(\frac{4}{5})^{3} \cdot (\frac{3}{10})^{- 2} \cdot (\frac{4}{3})^{- 4}

5 + - 9 - 7 + - 121
