simplify ((2x)/9)^2

Solution

simplify

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

\frac{4 x ^{2}}{81}

Solution steps

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

Apply exponent rule:

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

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

Simplify

(2 x)^{2} : 4 x^{2}

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

9^{2} = 81

= \frac{4 x ^{2}}{81}

x^{2} + 8 x + 3 < 0

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

0 < 6 x - x^{2} - 5

\frac{5}{- 5 - 3 3}
