How do you get the same base for the power

1 answer:

3 0

You use division

over 2 or 4 or 3 or 5 or 7 and so on
in this case 2 is good

64 = 2 * 2 * 2 * 2 * 2 * 2 ( use division) = 2^6

16 = 2 * 2 * 2 * 2 = 2^4

number reminder
64 0
32 0
16 0
8 0
4 0
2 0
1 1

so 64 = 2^6 (number of zeros) no reminder

Solution:

we have been asked to find

The expression is equivalent to $7/10-2/10$

we can simplify the given expression as below

$\frac{7}{10}-\frac{2}{10}=\frac{7-2}{10}\\ \\ \Rightarrow \frac{7}{10}-\frac{2}{10}=\frac{5}{10}\\ \\ \text{Simplify we get}\\ \\ \frac{7}{10}-\frac{2}{10}=\frac{1}{2}\\$
