Can someone please explain what solving in scientific notation is?

Step-by-step explanation:

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.

For example, instead of writing 0.0000000056, we write 5.6 x, 10^-9

Scientific notation is about how to write numbers in a standard way.

a number is always written as #. x 10ⁿ, where #.### is a number between -9 and +9.

So 3 is written as 3 x 10⁰

33 is written as 3.3 x 10¹

etc...

Answer is 50.

Step-by-step explanation:

Solving:

√64= √2x2x2x2x2x2 =√2^2 x2^2 x2^2 =2x2x2=8

√16 = √2x2x2x2 = √2^2x2^2 = 2x2 = 4

√-1 = i

Putting values:
