Solution steps

(1 + 5) (1 + 5)

Apply exponent rule:

aa = a^{2}

(1 + 5) (1 + 5) = (1 + 5)^{2}

= (1 + 5)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(1 + 5)^{2} = 1^{2} + 2 \cdot 1 \cdot 5 + (5)^{2}

= 1^{2} + 2 \cdot 1 \cdot 5 + (5)^{2}

1^{2} + 2 \cdot 1 \cdot 5 + (5)^{2} = 6 + 25

= 6 + 25
