simplify (7x^3)^3

Solution

simplify

(7 x^{3})^{3}

Solution

343 x^{9}

Solution steps

(7 x^{3})^{3}

Apply exponent rule:

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

(7 x^{3})^{3} = 7^{3} (x^{3})^{3}

= 7^{3} (x^{3})^{3}

7^{3} = 343

= 343 (x^{3})^{3}

Apply exponent rule:

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

assuming

a \geq 0

(x^{3})^{3} = x^{3 \cdot 3}

= 343 x^{3 \cdot 3}

Multiply the numbers:

3 \cdot 3 = 9

= 343 x^{9}
