簡約 (1+5^2)-16(1/2)^2

解

簡約

(1 + 5^{2}) - 16 (\frac{1}{2})^{2}

22

解答ステップ

(1 + 5^{2}) - 16 (\frac{1}{2})^{2}

規則を適用する:

(a) = a

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

= 1 + 5^{2} - 16 (\frac{1}{2})^{2}

5^{2} = 25

(\frac{1}{2})^{2} = \frac{1}{4}

= 1 + 25 - 16 \cdot \frac{1}{4}

数を足す:

1 + 25 = 26

= 26 - 16 \cdot \frac{1}{4}

16 \cdot \frac{1}{4} = 4

= 26 - 4

数を引く:

26 - 4 = 22

= 22
