Question

3. Write the following in the exponential form:
(1) bxbxbx... 15 times
​

Answer 1

Answer:

bxbxb........... and so on up to 15 times

therefore,B^15

Answer 2

Answer:

$b.b.b.b.b.b.b..... 15 times = b^{15}$

Step-by-step explanation:

$b = b^{1}$

$b.b = b^{(1+1)} = b^2$

$b.b.b = b^{(1+1+1)} = b^3$

$b.b.b.b = b^{(1+1+1+1)} = b^4$

$b.b.b.b.b = b^{(1+1+1+1+1)} = b^5$

From the trend:

$b.b.b.b.b.b.b..... n times = b^n$

∴ $b.b.b.b.b.b.b..... 15 times = b^{15}$
