\left(\frac{\frac{49}{4}}{7^{2}}\right)^{2}x=\left(\left(\frac{1}{2}\right)^{0}-5\times 0.3^{2}\times 0.5^{-1}\right)^{2}
Calculate \frac{7}{2} to the power of 2 and get \frac{49}{4}.
\left(\frac{\frac{49}{4}}{49}\right)^{2}x=\left(\left(\frac{1}{2}\right)^{0}-5\times 0.3^{2}\times 0.5^{-1}\right)^{2}
Calculate 7 to the power of 2 and get 49.
\left(\frac{49}{4\times 49}\right)^{2}x=\left(\left(\frac{1}{2}\right)^{0}-5\times 0.3^{2}\times 0.5^{-1}\right)^{2}
Express \frac{\frac{49}{4}}{49} as a single fraction.
\left(\frac{1}{4}\right)^{2}x=\left(\left(\frac{1}{2}\right)^{0}-5\times 0.3^{2}\times 0.5^{-1}\right)^{2}
Cancel out 49 in both numerator and denominator.
\frac{1}{16}x=\left(\left(\frac{1}{2}\right)^{0}-5\times 0.3^{2}\times 0.5^{-1}\right)^{2}
Calculate \frac{1}{4} to the power of 2 and get \frac{1}{16}.
\frac{1}{16}x=\left(1-5\times 0.3^{2}\times 0.5^{-1}\right)^{2}
Calculate \frac{1}{2} to the power of 0 and get 1.
\frac{1}{16}x=\left(1-5\times 0.09\times 0.5^{-1}\right)^{2}
Calculate 0.3 to the power of 2 and get 0.09.
\frac{1}{16}x=\left(1-0.45\times 0.5^{-1}\right)^{2}
Multiply 5 and 0.09 to get 0.45.
\frac{1}{16}x=\left(1-0.45\times 2\right)^{2}
Calculate 0.5 to the power of -1 and get 2.
\frac{1}{16}x=\left(1-0.9\right)^{2}
Multiply 0.45 and 2 to get 0.9.
\frac{1}{16}x=0.1^{2}
Subtract 0.9 from 1 to get 0.1.
\frac{1}{16}x=0.01
Calculate 0.1 to the power of 2 and get 0.01.
x=0.01\times 16
Multiply both sides by 16, the reciprocal of \frac{1}{16}.
x=0.16
Multiply 0.01 and 16 to get 0.16.
