simplify (x+2/5)^2

Solution

simplify

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

\frac{( 5 x + 2 ) ^{2}}{25}

Solution steps

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

Simplify

x + \frac{2}{5} : \frac{5 x + 2}{5}

= (\frac{5 x + 2}{5})^{2}

Apply exponent rule:

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

= \frac{( 5 x + 2 ) ^{2}}{5 ^{2}}

5^{2} = 25

= \frac{( 5 x + 2 ) ^{2}}{25}

5 x^{3} (2 x + 4 y)

\frac{a ^{2} y ^{3}}{a ^{5} y ^{7}}

(x + 7)^{2} - x (x + 14)

\frac{54}{27}
