simplify (2x^4)^2

Solution

simplify

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

Solution

4 x^{8}

Solution steps

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

Apply exponent rule:

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

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

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

2^{2} = 4

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

Apply exponent rule:

(a^{b})^{c} = a^{b c},

assuming

a \geq 0

(x^{4})^{2} = x^{4 \cdot 2}

= 4 x^{4 \cdot 2}

Multiply the numbers:

4 \cdot 2 = 8

= 4 x^{8}

Popular Examples

3 (x^{2} - 4) + 7 = - 2

(x-5)/((x-2)(x-9))<0

\frac{x - 5}{( x - 2 ) ( x - 9 )} < 0

simplify ((15a^5b^3))/((5a^2b))simplify

\frac{( 15 a ^{5} b ^{3} )}{( 5 a ^{2} b )}

(x+16)(x-63)>= 0

(x + 16) (x - 63) \geq 0

(2-(1-x))/3-x=1-2/3 x

\frac{2 - ( 1 - x )}{3} - x = 1 - \frac{2}{3} x
