expand (1+8)^{1/2}

Solution

expand

(1 + 8)^{\frac{1}{2}}

Solution

3

Solution steps

(1 + 8)^{\frac{1}{2}}

Add the numbers:

1 + 8 = 9

= 9^{\frac{1}{2}}

Factor the number:

9 = 3^{2}

= (3^{2})^{\frac{1}{2}}

Apply exponent rule:

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

(3^{2})^{\frac{1}{2}} = 3^{2 \cdot \frac{1}{2}} = 3

= 3
