Question

Please help me please lots of points

Answer 1

The answer in scientific notation would be 5×10^1 Which is 50 in standard notation

To get this you first look for you two numbers which are 1*10^21 and 5*10^22

However a key word in this word problem is how many times greater than

When you see this, you will divide so 1×10^21 ÷ 5×10^22 = 5×10^1

When you have your answer to convert it into standard notation you just add one 0 to the 5 giving you 50, because its only to a power of 1

Therefore, the diameter of the IC 1101 is 50 times greater than the diameter of the Milky way

Answer 2

50

uhh as each scientific notation is 10 more, so therefore 5 x 10

50
