What is 4.002 times 10 to the power of 2?

Answer 1

4.002 x 10 = 40.02

(40.02)^2 = 40.02 x 40.02

= 1601.6004 [4x4 =16. i.e 1600]

You can do it as (40 + 0.02)^2 == 1600 + 0.004 + 2 x 40 x 0.02(1.6)

(a+b)^2 = a^2 + b^2 + 2xaxb

Another Answer:- 4.002 times 10^2 = 400.2

If your question is (4.002 x 10)^2 = 1601.6004

if it's 4.002 x (10^2) its 400.2
