Expand a3b2 and a2b3. Are they equal?
4.
Express the following numbers in exponential form with the given base:
512, base 2
5.
Express 729 in exponential form.
1.
43 x 23 x 53 = (4 x 2 x 5)3 = 403 [Rule extended for 3 numbers]
2.
\(\frac { { 10 }^{ 8 } }{ { 10 }^{ 6 } } \) = 108-6 = 102
3.
a3b2 = (a x a x a) x (b x b)
a2b3 = (a x a) x (b x b x b)
Therefore, a3b2 ≠ a2b3
4.
512 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 29
5.
Dividing by 3, we get
729 = 3 x 3 x 3 x 3 x 3 x 3 = 36
Also, 729 = 9 × 9 × 9 = 93
