When dealing with huge exponents, the key to a clear solution is to break the problem down using factorization. By reducing the exponent to its prime components, you can then apply the power rule of exponents. Alternatively, if the exponent can be expressed as a sum of smaller integers, the product rule offers a simpler path. With a few practice problems, you’ll be able to choose the most efficient strategy for any situation.
For example, consider the exponent 24:
24 = 2 × 12 = 2 × 2 × 6 = 2 × 2 × 2 × 3
The power rule states that (x^a)^b = x^{a\times b}. Thus:
6^{24} = 6^{(2\times2\times2\times3)} = (((6^2)^2)^2)^3
Step by step:
(((((6^2)^2)^2)^3)
= ((36^2)^2)^3
= (1296^2)^3
= 1679616^3
= 4.738 × 10^{18}
Rewrite 24 as a sum of small, non‑trivial integers, e.g.:
24 = 12 + 12 = 6 + 6 + 6 + 6 = 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3
The product rule says x^a × x^b = x^{a+b}. Therefore:
6^{24} = 6^{(3+3+3+3+3+3+3+3)} = 6^3 × 6^3 × 6^3 × 6^3 × 6^3 × 6^3 × 6^3 × 6^3
6^{24}
= 6^3 × 6^3 × 6^3 × 6^3 × 6^3 × 6^3 × 6^3 × 6^3
= 216 × 216 × 216 × 216 × 216 × 216 × 216 × 216
= 46656 × 46656 × 46656 × 46656
= 4.738 × 10^{18}
