(1.5 x 10 squared)x(3.5 x 10 to the fifth power)

  2.03259656 × 10^8

Explanation:

1.5 x 10 = 15

√(15) = 3.87

put this to the side until we sum everything up..

3.5 × 10 = 35

35 ^ 5 = 52521875

So, now lets sum it all up

(3.87) x (52521875) = 203259656.25

but in scientific notation it is:  2.03259656 × 10^8
