Step-by-step explanation:
may be those can be QT and QN
2x+38=50
2x+38-38=50 -38
2x =12
2x/2 =12/2
x=6
Basically what you do is (the ^ arrow meaning exponent)
You take 3.7 + 4.45 x 10^20
Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20
815 x 10^18 = <span>815000000000000000000</span>
