What is 8.1 times 10 to the tenth power?

Answer 1

according to siri its 10000000000 or 10^10

Answer 2

When you put 10 to any power, you just get a one followed by the number of zeroes represented by the exponent:
8.1 x 10,000,000,000 = 81,000,000,000
If you do not understand, you can always just use a calculator.
Hope this helps!
