8x=\left(3.5-2.8\right)^{22}
Combine 3x and 5x to get 8x.
8x=0.7^{22}
Subtract 2.8 from 3.5 to get 0.7.
8x=0.0003909821048582988049
Calculate 0.7 to the power of 22 and get 0.0003909821048582988049.
x=\frac{0.0003909821048582988049}{8}
Divide both sides by 8.
x=\frac{3909821048582988049}{80000000000000000000000}
Expand \frac{0.0003909821048582988049}{8} by multiplying both numerator and the denominator by 10000000000000000000000.
