Jawaban:

$\sf{f(x)\sqrt[3]{\sqrt{100}\times\frac{5}{2}\times4})=11\sqrt[3]{100}}$

Penjelasan dengan langkah-langkah:

f(x) = 9x + 7x - 5x

f(x) = (9+7-5)x

f(x) = (16-5)x

f(x) = 11x

$\sf{f(\sqrt[3]{\sqrt{100}\times\frac{5}{2}\times4}=11\sqrt[3]{\sqrt{100}\times\frac{5}{2}\times4}}$

$\sf{f(x)\sqrt[3]{\sqrt{100}\times\frac{5}{2}\times4}=11\sqrt[3]{\sqrt{{10}^{2}}\times\frac{5}{\cancel{2}}\times\cancel{4}}}$

$\sf{f(x)\sqrt[3]{\sqrt{100}\times\frac{5}{2}\times4})=11\sqrt[3]{10\times5\times2}}$

$\sf{f(x)\sqrt[3]{\sqrt{100}\times\frac{5}{2}\times4})=11\sqrt[3]{100}}$

...

f(x) = 9x + 7x - 5

f(x) = 11x

$x = \sqrt[3]{(\sqrt{100}\times \dfrac{5}{2} \times4)} \\ x = \sqrt[3]{10 \times \frac{5}{2} \times 4} \\ x = \sqrt[3]{100} \\ x = {10}^{ \frac{2}{3} }$

$f( {10}^{ \frac{2}{3} }) = 11 \times {10}^{ \frac{2}{3} } \\ \: \: \: \: \: \: = {110}^{ \frac{2}{3} }$
