simplify (-5x)^4

Solution

simplify

(- 5 x)^{4}

625 x^{4}

Solution steps

(- 5 x)^{4}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 5 x)^{4} = (5 x)^{4}

= (5 x)^{4}

Apply exponent rule:

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

(5 x)^{4} = 5^{4} x^{4}

= 5^{4} x^{4}

5^{4} = 625

= 625 x^{4}

a^{3} x^{2} - 5 a^{3} x + 6 a^{3} + x^{2} - 5 x + 6

(8^{x})^{x} - 8^{x} - 3

x^{2} - 3 x y

\frac{x}{5} - \frac{( x - 2 )}{3} + x

l (sin^{3} (t) - cos^{2} (t) + sin^{2} (t) + cos^{3} (t))
