Question

Express 49×49×49×49×49 in exponential form as power of 7 is

Answer 1

Step-by-step explanation:

72×72×72×72×72

use the property of indices :

{s}^{m} \times {s}^{n} = {s}^{m + n}sm×sn=sm+n

so the powers will get add up

{7}^{2 + 2 + 2 + 2 + 2}72+2+2+2+2

and your answer will be :

{7}^{10}710
