r^{0.2}r=17.22

解

r^{0.2} r = 17.22

解

r = 6 \frac{4.73168 E 14}{312500000}, r = - 6 \frac{4.73168 E 14}{312500000}

+1

十進法表記

r = 10.71587 \dots, r = - 10.71587 \dots

解答ステップ

r^{0.2} r = 17.22

equationの両辺を以下の累乗にする:

5 : r^{6} = 1514138.96435 \dots

r^{6} = 1514138.96435 \dots

解く

r^{6} = 1514138.96435 \dots : r = 6 \frac{4.73168 E 14}{312500000}, r = - 6 \frac{4.73168 E 14}{312500000}

r = 6 \frac{4.73168 E 14}{312500000}, r = - 6 \frac{4.73168 E 14}{312500000}

解を検算する:

r = 6 \frac{4.73168 E 14}{312500000}

真

, r = - 6 \frac{4.73168 E 14}{312500000}

真

解答は

r = 6 \frac{4.73168 E 14}{312500000}, r = - 6 \frac{4.73168 E 14}{312500000}

0.4x^{0.5}+5=38

0.4 x^{0.5} + 5 = 38

x^{- \frac{1}{2}} = 7

\sqrt[3]{2x+11}=1

3 2 x + 11 = 1

sqrt(x)=7sqrt(2)

x = 72

1.5=2.14(x-0.75)^{3/2}

1.5 = 2.14 (x - 0.75)^{\frac{3}{2}}
