Answer:
Explanation:
The answer is B
if you have 2^3 * 2*4 to find out what that equals, leave the base (2) alone and add the powers. You get 2^(3 + 4) = 2^7
Let's see if that works.
2^3 = 8
2^4 = 16
8 * 16 = 128
Now what is 2^7?
2^7 = 128 just as it should
Now returning to your question
3^7.869 = answer B You leave the base alone (7) and add the powers. The 8 is 8/10
The 6 is 6/100
The 9 is 9 / 1000 Just add the fractions and keep the 7 and the 3.
