simplify (5x^7)^2

Solution

simplify

(5 x^{7})^{2}

Solution

25 x^{14}

Solution steps

(5 x^{7})^{2}

Apply exponent rule:

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

(5 x^{7})^{2} = 5^{2} (x^{7})^{2}

= 5^{2} (x^{7})^{2}

5^{2} = 25

= 25 (x^{7})^{2}

Apply exponent rule:

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

assuming

a \geq 0

(x^{7})^{2} = x^{7 \cdot 2}

= 25 x^{7 \cdot 2}

Multiply the numbers:

7 \cdot 2 = 14

= 25 x^{14}
