The POWER function works like an exponent in a standard math equation. So 10×10 = 100, the second power of 10. Lv 7. Note the pattern: A negative number taken to an even power gives a positive result (because the pairs of negatives cancel), and a negative number taken to an odd power gives a negative result (because, after cancelling, there will be one minus sign left over). In mathematical terms, 2 is the base and 2 is the exponent as follows: 2 2 The problem above (2 to the 2nd power) means that you multiply 2 by itself. The POWER function can be used to raise a number to a given power. 0 0. 46.2×10⁻² = 46.2/10² = 46.2/100 =0.462.
