factor 81n^4-25

factor

81 n^{4} - 25

(9 n^{2} + 5) (9 n^{2} - 5)

Solution steps

81 n^{4} - 25

Apply exponent rules

= (9 n^{2})^{2} - 5^{2}

Apply Difference of Two Squares Formula:

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

(9 n^{2})^{2} - 5^{2} = (9 n^{2} + 5) (9 n^{2} - 5)

= (9 n^{2} + 5) (9 n^{2} - 5)

lo g_{\frac{1}{3}} (27)

\frac{- 3 - 4}{- 3 + 7}

16 x y + 12 x + 12 y + 9

a^{2} + 4 a - 5

640 - 10 \times 2
