Is there an easy way to do 1.03^8, than multiplying 1.03 8 times? I am slow at calculations

The GMAT won't ask you to calculate that number, maybe you need just an approximation...

(1.03)^8=(1.03)^4(1.03)^4=(1.03)^2*(...)=(1+0.03)^2*(...)=(1+0.0009+0.06)*(...)=~(1.06)(1.06)(1.06)(1.06)=~1.12*1.12=~1.25
