simplify the expression

3.2 × 10^5 + 1.25 × 10^4 + 2.9 × 10^5
show your work.

(9−7)^3(5^0)+(8+3)^2
=(2^3)(5^0)+(8+3)^2
=8(5^0)+(8+3)^2
=(8)(1)+(8+3)^2
=8+(8+3)^2
=8+11^2
=8+121
=129

3.2(10^5)+1.25(10^4)+2.9(10^5)
=(3.2)(100000)+1.25(104)+2.9(105)
=320000+1.25(10^4)+2.9(10^5)
=320000+(1.25)(10000)+2.9(10^5)
=320000+12500+2.9(10^5)
=332500+2.9(10^5)
=332500+(2.9)(100000)
=332500+290000
=622500
