Perform the following addition subtraction problem.s Be careful about operations and parenthesis.
(3.5*10^3)(4.2*10^5)+(4.3*10^-4)(2.1*10^-2)
A little confused...
Please Help,,, thanks
(3.5*10^3)(4.2*10^5)+(4.3*10^-4)(2.1*10^-2)
= (3.5*4.2)*10^(3+5) + (4.3*2.1)*10^(-4-2)
= 14.7*10^8 + 9.03*10^-6
= 1470000000 + 0.00000903
= 1470000000.00000903
