simplify (8x^2)^2

Solution

simplify

(8 x^{2})^{2}

Solution

64 x^{4}

Solution steps

(8 x^{2})^{2}

Apply exponent rule:

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

(8 x^{2})^{2} = 8^{2} (x^{2})^{2}

= 8^{2} (x^{2})^{2}

8^{2} = 64

= 64 (x^{2})^{2}

Apply exponent rule:

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

assuming

a \geq 0

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

= 64 x^{2 \cdot 2}

Multiply the numbers:

2 \cdot 2 = 4

= 64 x^{4}
