Question

what is 4,000+702 in standerd form

Answer 1

Answer:

4.702×$10^{3}$

Step-by-step explanation:

• 4702 is in numerical form to make it standard form it has to be in the format
• a×$10^{b}$      where  1≤a<10
• So a would equal 4.702 in this situation so we have
• 4×$10^{b}$
• To work out b, you see how many places the decimal point moved to the left or the right.
• If the decimal point moves to the left it is a positive b, if it moved to the right it is a negative b. In this case it is a positive b.
• It moved 3 places so it would be
• 4.702×$10^{3}$
