What is the units digit of 2 to the 50th power
11111nata11111 [884]
Notice that

2^1=2
2^2=4
2^3=8
2^4=16
2^5=32

so that for each power of 2, there is a pattern of period 4. This means that for integers k\ge0, each of 2^{4k}, 2^{4k+1}, 2^{4k+2}, and 2^{4k+3} have the same units digit.

We can write 50=4(12)+2, and since 3=4(0)+2, it follows that 2^{50} and 2^3 share the same units digits. So the units digit of 2^{54} is 8.

If the diameter of a circle with a circumference of 19.5 inches is reduced by three, what would be the circumference of the new
Elanso [62]

It is given that the circumference of the circle is 19.5 inches. Let the diameter is d inches .

And the formula of circumference is

C= \pi d

Substituting the value of C, we will get

19.5= \pi d&#10;\\&#10;d = \frac{19.5}{ \pi}

When the diameter increased by 3, then the circumference is

C = \pi ( \frac{19.5}{ \pi} +3})=Approx 29 inches

And the circumference , when diameter is increased by 3 is 29 inches .
