Question

bracket 25 power 3 into 25 power 7 bracket divide 25 power 10

Answer 1

(25)^3 +×(25)^7×(25)^10
bases are equal then power should be added
(25)^3+7+10
(25)^20
=9.0945×10^27

Answer 2

Given
$= {25}^{3} \times {25}^{7} \div {25}^{10}$
using
${a}^{m} \times {a}^{n} = {a}^{m + n}$
we can write

=
${25}^{3 + 7} = {25}^{10}$
that is = 25^10/25^10

= 1

Hope this helps you....✌^_^
