Break the problem up into groups of 2 10, with the final term being 2 x where x < 10 (if needed). With 2 27, you'd think of that number as 2 10 × 2 10 × 2 7. Next, replace the final power with its actual total. 2 7 = 128, so the problem is now 2 10 × 2 10 × 128. Now you replace each 2 10 with 10 3. Our problem now becomes 10 3 × 10 3 ×
We choose a very specific number: 10 10 10 to the power equal to the number of digits after the decimal dot in the number with more of them. In other words, the multiplier consists of 1 1 1 and as many zeros as the " longer " number has digits after the dot.
David Severin. 2 years ago. The rule for dividing same bases is x^a/x^b=x^ (a-b), so with dividing same bases you subtract the exponents. In the case of the 12s, you subtract -7- (-5), so two negatives in a row create a positive answer which is where the +5 comes from. In the x case, the exponent is positive, so applying the rule gives x^ (-20
Answer: 10 to the power of 5 is 100000. Exponents Calculator. Please enter the base (b) and a exponent (n) to calculate b n: to the power of = ? Calculate. Notes: i) e (Euler's number) and pi (Archimedes' constant π) are accepted values. ii) 1.2 x 10 3 should be entered as 1.2e3 and iii) 1.2 x 10-3 as 1.2e-3.When x molecules are removed from 200 mg of N 2 O, 2.89×10-3 moles of N 2 O are left. x will be . a.10 20 molecules. b.10 10 molecules. c.10 21 moleculesa × 10 b. where the exponent b is an integer, and the coefficient a is any real number (called the significand or mantissa). E Notation. E notation is a type of scientific notation in which the phrase "times 10 to the power of" is replaced by the letter E or e; for example, 1.2 × 10 5 is written as 1.2E+5 or 1.2e5 and 7.4 × 10-8 is
As the exponent is a positive integer, exponentiation means a repeated multiplication: 4 to the 20th power =. The exponent of the number 4, 20, also called index or power, denotes how many times to multiply the base (4). Thus, we can answer what is 4 to the 20th power as. 4 to the power of 20 = 420 = 109 9511627776.
