9-2 = 1/92 = 1/81
eight to the second power equal to 64
81 divided by 9 ie 9
No because it's ninety-nine one hundredth of a second.
Just X to the second power minus nine. You can't subtract nine from x to the second power unless you know what x is.
The exponent is TWO.
Nine to the power of five is basically 9x9x9x9x9. 9x9x9x9x9= 59049 Hope it helps x
