Question

A gigameter is 1.0x10 to the 6th power how many square kilometers are in 5 square gigameters?

Please answer in scientific notation

Answer 1

Answer:

1 Giga-meter = 1.0 x 10 to the power of 6

= 1 x 10 to the power 6

= 10, 000 kilometers

If 1 Giga-meter =10,000 kilometers

Then,

5² Giga-meter =(5 x 10,000 kilometers)²

Hence 50,00,00,000 kilometer²

Which gives 5 x 10 to the power 7

~Final answer 5x10 to the power 7~

Hope this helps you:-)
