Find (2 × 10^7) + (3 × 10^4).
a) 2.003 × 10^4
b) 2.003 × 10^7
c) 2.03 × 10^4
d) 2.03 × 10^7

( 2 x 10^7) + ( 3 x 10 ^4)

you can change each of them back to the normal form

i,e 2 x 10^7 = 20000000

    3 x 10 ^4 = 30000

then add, i.e 20,000,000 + 30,000 = 20,030,000

convert back to standard form

which is 2.003 x 10^7

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
