simplify (sqrt(x^2-4))^4

Solution

simplify

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

Solution

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

Solution steps

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

Rewrite

4

as

2 \cdot 2

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

Apply exponent rule:

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

assuming

a \geq 0

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

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

Apply exponent rule:

assuming

n i s o dd or a \geq 0

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

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